Chapter 798 Before the Exam
February 2th, Thursday morning, the third class, mathematics class.
Gao Heshuai spoke in a resonant voice: "Let's look at the last question. The mathematics department of a certain university plans to hold a psychological test activity with different themes on Saturday and Sunday, respectively led by Teacher Li and Teacher Zhang. It is known that there are n students in the department..."
“(I) Find the probability that Student A in the department receives the activity notification information sent by Teacher Li or Teacher Zhang;
(II) Find the integer m that maximizes P(X=m).
After reading the question, Gao Heshuai paused, and used the inductive method to list the process and answer of the first question.
When it came to the second question, he quickly read out the answer and then threw away the chalk.
Relaxed and announced: "Okay, this test is over."
The students were all confused. Yu Wen raised her hand and said, "Teacher Gao, you explained every question before, why didn't you explain this one?"
Gao Heshuai glanced at Yu Wen and said, "This is the final question of the science mathematics exam in our province in 13. You wouldn't understand even if I explained it to you."
Yu Wen was choked: "There must be someone who can understand, right?"
Gao Heshuai looked at Xue Yuantong, Jiang Ning, and Chen Qian, and said, "Those who can understand don't need me to explain."
"I sincerely advise everyone that if you encounter questions you don't understand in the college entrance examination, don't look at them, solve other questions, get the points you can get, and don't aim too high!"
After giving a few words of instruction, Gao Heshuai left Class 8 with a cup of tea.
Yu Wen complained from her seat: "This is too much! Fatty Gao has no sense of responsibility at all! Yanan, don't you agree?"
Jiang Yanan thought what Teacher Gao said was very good, but on the surface, she still agreed with the little sister.
After Gao Heshuai left, the classroom became messy again.
Duan Shigang in the first row did not give in to depravity. In order to avoid a tragic fate, Duan Shigang has been studying very hard recently. As a sophomore in high school, he has mastered the mathematics knowledge of a junior high school.
When he encountered something he didn't know, he asked his classmates for help. Of course, he couldn't ask Wu Xiaoqi for help because Wu Xiaoqi was even worse than him.
Duan Shigang held up a junior high school exercise book, turned around and asked Chai Wei: "Awei, look at this question, why is the answer I calculated different from the real answer?"
【If a=a, then a = ？】
Duan Shigang’s answer is: a=a.
Although Chai Wei is gloomy, he is not completely annoying and can still chat with others. When faced with Duan Shigang who asked him for help, Chai Wei did not tell him to get lost. After all, Brother Gang looks quite capable.
Chai Wei: “Wrong, the answer is a=0 or a=±1.”
Duan Shigang was depressed: "How can it be equal to this? Aren't the previous ones the same?"
Chai Wei stared at him and said, "You like Zhou Jinglan, does that mean Zhou Jinglan likes you?"
Duan Shigang turned around cursing.
The location of the four major seats.
Chen Siyu counted on her fingers: "According to our school's arrangement, the final exam will be tomorrow, which will last for two days, and then it will be winter vacation. Oh my god, even after the exam, there are still 10 days until the Chinese New Year!"
"If you add the holiday after the New Year, doesn't that mean we have 20 days off?" Chen Siyu couldn't believe it. Are she and her sister going to fly into the sky when she's unhappy?
Xue Yuantong was playing an online tank battle game. She was very excited to fight against others and did not forget to respond: "Yes, I can sleep for 20 days. It's so cool!"
Facing the upcoming winter vacation, Chen Siyu was extremely excited. Of course, she did not forget that if she wanted to have a wonderful winter vacation, she must get good grades so that she could continue to sit with Bai Yuxia next year.
After all, there are countless people in this class who are greedy for Bai Yuxia!
She wants to protect the best Xia Xia!
Chen Siyu found out the math problem that Teacher Gao was unwilling to explain just now. Since the teacher was unwilling to explain it to her, she asked Jiang Ning for help!
"Tongtong, can we change seats? I want to discuss a question with Jiang Ning." Tongtong blocked the meeting between Chen Siyu and Jiang Ning.
Xue Yuantong was playing a game: "Can't I tell you?"
Chen Siyu was embarrassed: "But, you are playing games."
"It's okay, just tell me, which question?" Xue Yuantong put down his phone generously.
So next, Xue Yuantong began to explain the question to Siyu.
This time, Tongtong treated Siyu like an elementary school student and explained each step separately in an extremely detailed manner, which was completely different from his usual perfunctory approach.
Chen Siyu lowered her head, immersed in the calculations, and gradually figured out the first question. She was so happy that she was dying.
Surprised, she looked up and thanked Tongtong.
It turned out that Tongtong was driving a tank, dodging various moves, and fighting fiercely with the enemy, and then he explained the problem-solving process to her with a very clear mind.
Chen Siyu was stunned for a moment, and suddenly she understood why her grades were so good.
……
After one class of in-depth mathematics learning, Duan Shigang felt that he had achieved great success. When he walked, he felt that he had gained the power of knowledge. He briefly gained the buff of loving learning.
But he had a bad side. After reading a little, he began to look down on others. Duan Shigang looked down on his unlearned deskmate: "Xiao Qi, if you don't study every day, what will you do in the future?"
Wu Xiaoqi looked surprised and thought he was weird.
Duan Shigang wandered to the back row, full of confidence: "Brothers, when I go to college, should I study computer science or finance?"
Cao Kun said: "Computers, mobile Internet is so advanced now."
Song Sheng, who was throwing away the garbage, looked at him with his small eyes: "It's better for you to learn something down-to-earth like auto repair. Don't you also know how to modify a ghost fire? Isn't this professional?"
Duan Shigang was furious: "Fuck, why do I have to deal with gasoline every day?"
Song Sheng: "Haha, then you should work hard, get into a 211 university, and study mechanical automation."
Duan Shigang debated with him on all kinds of industries.
Song Sheng was too lazy to talk to him and said, "No matter what choices children from ordinary families make, they will end up in a mess."
After he finished speaking, Song Sheng added: "Wu Xiaoqi's parents just bought someone a house in Shanghai. Think about it carefully. Can you afford one after working hard all your life?"
Duan Shigang has seen the true face of society. He was persuaded to drop out of the factory and then return to school. When he heard this, he felt particularly powerless.
Guo Kunnan stood up and said indignantly: "What is there to be envious of? That's just what his parents gave him now!"
Song Sheng: "Indeed, his parents will give more in the future."
"Grass!"
Guo Kunnan suffered a heavy blow and felt uncomfortable: "..."
Seeing her classmates depressed, Xin Youling comforted them: "Happiness has a threshold. Everyone's happiness is different. How much food can a person eat in his lifetime, how much can he get..."
Song Sheng glanced at Xin Youling and interrupted her: "Squad leader, have you ever worried about material things?"
Xin Youling was stunned for a moment and said, "No."
Although her family is not wealthy, they live in one of the best communities in the city. She has basically everything she wanted since she was a child, including the latest mobile phones, computers, shoes and clothes. She has never worried about material things.
When she was in the third grade of elementary school, she had a conflict with her parents and ran away from home. At that time, she only had a pitiful 5,000 yuan in New Year's money.
After satisfying her material happiness, Xin Youling pursues spiritual abundance. When she waves her hand, the whole class obeys her orders and stands on her side. The satisfaction she feels is incomparable!
Song Sheng saw through the class monitor's inner thoughts. People like the class monitor would never understand the helplessness of ordinary high school students trapped in material things, the desire to replace their cell phones with non-stuck ones, to buy a pair of brand-name shoes, to add a braised egg and a braised sausage to their flat noodles.
Song Sheng shook his head: "Everyone is ignorant, but I am the only one who is clear-headed!"
Like a poet, he left the back row.
After the heart-breaking king Song Sheng left, the atmosphere in the back row became much more depressing. Duan Shigang said: "If a road is blocked, use points to break it!"
At this moment, he regained his former ambitious demeanor. Yes, in another year and a half, he will rewrite his life!
Duan Shigang found Xue Yuantong, who was first in the class, first in the school, and even first in the city.
He asked, "Xue Yuantong, I want to ask you a question. My math grades have always failed, so do you know how to get 140 points?"
Xue Yuantong tilted his head and said seriously: "Do two fewer multiple-choice questions."
Duan Shigang left dejectedly.
His high spirits were shattered in an instant.
……
afternoon.
Dongdong’s grandmother rode her electric scooter back to the bungalow.
Seeing Dongdong making a snowman in the snow, Dongdong's grandmother howled, "My grandson, I finally stopped pulling your broken tire!"
Is it because the food is not available? There were no guests coming to the farmhouse for lunch.
When Dongdong saw his grandmother, he didn't even say hello and just squatted on the ground to make a snowman.
At this time, Teacher Qian smiled sinisterly and moved closer to Dongdong's grandmother.
"You shifty guy, get out of here!" Dongdong's grandmother felt disgusted when she saw him like this!
Teacher Qian's mouth twitched. If it wasn't for the purpose of killing someone with a borrowed knife, he would definitely turn around and leave!
Trying to suppress his nausea, Teacher Qian said, "Guess why Dongdong likes to pull tires, and guess who threatened him?"
Dongdong's grandmother did feel something was wrong, so she called Dongdong over and asked him in person.
Taking this opportunity, Teacher Qian kept his achievements and fame to himself, preparing for a good show.
Unexpectedly, the next moment.
Facing grandma's question, Dongdong answered loudly: "I volunteer, I volunteer!"
Teacher Qian was dumbfounded. What the hell? Jiang Ning beat Dongdong so badly last night, and Dongdong didn’t even dare to complain?
His cognition was subverted.
Dongdong didn't get any information. When she passed by Teacher Qian's house, she spit at him.
Teacher Qian wiped his face and felt so angry that his teeth were itching.
Soon, to the west of the bungalow, a titanium-gray electric vehicle drew a gorgeous arc. Jiang Ning and Xue Yuantong were back!
Dongdong saw this and ran to Jiang Ning in fear. From a distance of three meters, he timidly demanded the money: "Pay me back my labor fee yesterday. 1 cents per trip!"
He made 16 trips yesterday and earned 80 yuan. Logically, he should get a share of 1 yuan.
Jiang Ning chuckled. As expected, after a beating, Dongdong began to understand what was happening.
Jiang Ning sat on the electric bike and counted ten 1-cent coins. He threw them at Dong Dong and hit him in the face.
Dongdong was hit and became furious on the spot, but he didn't dare to get angry and quickly lowered his head to pick up the money.
Jiang Ning hit him slowly, one penny at a time, which was so hateful.
Dongdong was hit many times, but he didn't mind. Teacher Qian couldn't stand it anymore and said, "If you have the guts, throw a piece!"
Jiang Ning really changed it into a one-yuan coin, and soon he got twenty or thirty yuan.
Teacher Qian held it in for a while without saying anything, only regretting that it wasn't him who was hit.
……
Afternoon, boys' dormitory.
"Pang Jiao, haha, is she worthy of being compared with me?" Zhao Xiaofeng sneered, then he lit a cigarette and smoked it slowly.
It all started when they were discussing the heroes of No. 8 Middle School, and Duan Shigang mentioned Pang Jiao from Class .
Zhao Xiaofeng is now the number one figure among the poor students in No. 4 Middle School. He is highly appreciated by Brother Tian. He usually smokes soft Zhonghua cigarettes, which shows that he is very capable.
Ge Hao flattered him: "Yeah, Pang Jiao is nothing, Boss Zhao gives the order!"
Zhao Xiaofeng was photographed very coolly.
Ge Hao suggested: "Brother Zhao is here to observe today. I'm sorry to show off. Let's shout a few words to Brother Zhao and shoot a video to post on Kuaishou!"
When Zhao Xiaofeng heard it, he thought it was a good idea.
Ge Hao clapped his hands and shouted, "One, two, three!"
Then he started shouting: "After ten years of fighting in the army, I felt lonely and retired to the mountains!"
Zhao Xiaofeng sat on the edge of the bed, inhaling and exhaling smoke, which gradually enveloped his face. Accompanied by dynamic rap, he looked like a king.
After the filming, Ge Hao was particularly considerate and added a dark and cold filter. Zhao Xiaofeng was very satisfied after seeing it and rewarded Ge Hao with 50 yuan for his hard work.
Ge Hao was very happy. After confirming that the video was great, he clicked to post it on Kuaishou and also thoughtfully added the address.
When Duan Shigang saw this scene, he felt particularly uncomfortable. In the past, the one who enjoyed all this was his brother Gang!
Duan Shigang left the boys' dormitory with mixed feelings. His heart was so lonely.
……
The first class of evening self-study.
This is the last evening self-study class of this semester. There is an inexplicable atmosphere in the classroom, with both the pressure of the final exams and the excitement of facing the holidays.
The students gradually became chaotic, and Xin Youling's management also became much lax.
At this moment, a voice came from the loud speaker: "
This afternoon, Zhao Xiaofeng, a student of our school, smoked in the male dormitory area without permission and uploaded the video to the Kuaishou APP, which caused a negative impact. In order to maintain strict school discipline... Zhao Xiaofeng was given the punishment of staying in school for observation..."
Suddenly, the whole school was in an uproar!
Chen Siyu was puzzled: "How can there be such a stupid person who smokes and posts videos?"
In this environment, Jiang Ning used shaved wood to set up a mini stove. He cut open an empty Coke can, leaving the bottom of the can as a small pot, and placed it on a wooden stand.
Then, Jiang Ning lit a candle, placed it at the bottom of the jar, and poured some oil.
Under the burning of the small flame, the oil quickly heated up. Jiang Ning took out the peanuts he grew in Huqi Mountain from his pocket, peeled them, put them in a mini pot, and started frying the peanuts.
He held a small spoon in his hand and fried the peanuts evenly, while using his spiritual power to cover them to prevent the oil from splashing.
Tongtong on the left, Siyu on the right, and Jiang Yanan in front, all leaned forward to watch him frying peanuts, and they were quite shocked.
"You can still do this in the classroom? You're killing yourself!"
With the crackling sound, the aroma of peanuts wafts out.
Jiang Ning picked up the crispy peanuts one by one and placed them on the shell of the Coke can that he had opened earlier. He took out a small packet of salt and sprinkled it evenly.
Tongtong whispered to Siyu, "I will definitely be the first one."
