"There are seven balls in a bag, ah, three red balls, four black balls, so what is the equivalent of taking three balls from the bag and putting them back on the ground?"

Li Meng said while writing on the blackboard, Wang Yidi just raised his hand.

Qiao Yingjun replied gracefully: "It is equivalent to doing three independent repeated tests." ”

Li Meng also saw Wang Yidi raise his hand, but he didn't say anything, because he had already said it before, he didn't need to raise his hand in the third year of high school, he still raised his hand.

"And every time you take out the red ball...?"

"Three-seventh."

"Hey, blackball's....?"

"Four out of seven"

"Let event A be equal to taking out two red balls and one black ball, then..."

Li Meng and Qiao Yingjun asked and answered, and Lin Leier couldn't answer the question if she wanted to.

Qiao Yingjun waited for the teacher to finish the question every time, and then said the answer, and Lin Leier couldn't grab it if she wanted to.

"Okay, the second question is distributed as an after-school homework, this question is the unified examination of last year's DC midterm exam, and it is also the key knowledge point of this midterm exam, so let's go back and do a good job, and answer questions tomorrow, okay?" Li Meng wrote the last question on the blackboard and left it as homework.

Li Meng saw that the students below were about to get out of class, and immediately said: "Wait a minute, wait a minute, I'll say a few words." ”

The students in the class all sat down together.

"This mid-term exam, we have begun to move in different classes, and there are a lot of students in the parallel class, and they are working very, very hard to get into our sprint class, so you must be fully prepared for review, you know?"

As soon as Li Meng finished speaking, the students below said, "Got it." ”

Li Meng asked again at this time: "Let me ask, why didn't this Qiao Yingzi come?" Does anyone know what's going on? ”

Li Meng looked at Qiao Yingjun, who was bowing his head, and asked, "Qiao Yingjun, don't bow your head, let me ask you, what's the matter with Qiao Yingzi, why didn't you come?" ”

Qiao Yingjun was about to speak, Wang Yidi raised his hand and said, "Teacher, she hasn't been here for several days." ”

"Okay, I know, okay, let's get out of class." Li Meng was about to leave after speaking.

Qiao Yingjun was Wang Yidi's tablemate, sitting behind Huang Zhitao, Qiao Yingjun glanced at Wang Yidi when he stepped forward, and hurriedly shouted: "Teacher, I have something to tell you." ”

"Tell me, what's going on?"

"That, Yingzi has a cold, didn't the family ask you for leave?"

"No, Teacher Song didn't say it, is the cold serious? Nothing. ”

"It's okay, it's okay, I guess I'll go to the hospital to hang water, then I'll let the family call you later."

"Okay, fight early in the future, or I'm worried about dying, you go back and tell your parents."

"Hey, hey, I know, teacher, you go slowly."

Li Meng didn't delay the classmates after knowing what was going on, so he left with the textbooks.

Huang Zhitao glanced at Wang Yidi fiercely in his seat.

Wang Yidi said in a humble heart: "What, what are you doing?" She, she didn't come in the first place. ”

Huang Zhitao glanced at Wang Yidi after hearing this, and planned to ask Qiao Yingjun what was going on.

After Qiao Yingjun sent Li Meng off, he walked up to Wang Yidi with a gloomy face, and put it in Wang Yidi's ear and said, "It's you?" I'm her brother, can I not know what's going on? Why are you in such a hurry to behave? You'd better not plant it in my hands, catfish! Fish! Essence! ”

Wang Yidi thought that Qiao Yingjun was going to whisper at first, but after hearing it, he didn't, when he heard the catfish essence that Qiao Yingjun said at the end, he got up and slapped the table and pointed at Qiao Yingjun and said, "Qiao Yingjun, I'm not done with you!" ”

After saying that, he cried and ran away.

All the students in the class looked at Qiao Yingjun, and they didn't know what Qiao Yingjun said, but they could actually make Wang Yidi cry.

Qiao Yingjun saw everyone in the class looking at him, and shouted, "What are you looking at?" There's nothing to do, is there? It's all going to be, isn't it? I'll say it one last time, whoever chews my tongue for me again, pulls my wife's tongue, let me know, I tore him/her mouth! ”

In the class, except for Huang Zhitao, he didn't speak, and immediately began to bury his head in reading, not daring to look at this 'evil god', Qiao Yingjun really came out, the teacher's treasure, the rich second generation, and he studied martial arts, and he also won awards, he was afraid.

Qiao Yingjun has been in a bad mood these days, and he didn't wake up every day, but he was woken up by the big rooster, and he was worried that he had no place to vent his anger, and he hit someone at the gun.

Qiao Yingjun sat in his position with a dark face, Huang Zhitao turned around and saw that Qiao Yingjun's face was very bad, and he didn't know whether to ask or not.

After hesitating, he still stubbornly asked in a low voice, "Why didn't Yingzi come again?" ”

Qiao Yingjun saw that it was Huang Zhitao, and complained in a low voice: "Didn't my dad move back recently, she said every day that she was under pressure, and she played Lego at my dad's, and let me go up every day." ”

Huang Zhitao understood what was going on and said; "Then I'll organize my notes and give it to her when she comes."

Qiao Yingjun nodded.

Lin Lei'er happened to come back from going to the toilet outside, walked up to Qiao Yingjun and said, "Brother Handsome, just now Teacher Li asked me and my cousin, and asked what was wrong with Yingzi, and we told Teacher Li that Yingzi had a cold, don't forget to tell her, don't goof." ”

When Qiao Yingjun heard that it was Lin Lei'er, he smiled and said to Lin Lei'er: "Okay, thank you Lei'er." ”

Lin Leier smiled happily and returned to her seat to read.

Someone in the class whispered: "Why is this 'evil god' talking and laughing at Lin Lei'er." ”

"People's cousin Fang Yifan and 'Evil God' are small, and Qiao Yingzi is also small, isn't it good for him."

Qiao Yingjun has excellent hearing, got up and walked to the table between the two of them and knocked on it, and said fiercely: "Are you two redundant?" What did I just say? ”

"That...."

"That, class leader, we said that Mr. Li left the math problem just now."

Qiao Yingjun knew that the two of them were afraid of themselves, and finally warned: "If you two tell me a little talk again, I will let you know why the flowers are so red!" ”

"Hey, got it."

The two classmates looked like dogs, and immediately nodded in agreement, I'm really afraid.

After Li Meng finished confirming with Qiao Yingjun, she happened to meet Fang Yifan who came out of the bathroom and asked, and then Lin Leier also came out and asked again.

That's when Lin Leier came back to make a report.

When Qiao Yingjun was talking about the two classmates, Li Meng received Qiao Weidong's voice, saying that Qiao Yingzi had a cold and might have to go to school later.

After listening to the voice, Li Meng put his mobile phone in his pocket and muttered, "I'm really sick." ”

(There's no school violence.,I hope you don't get me wrong.,It's just to show that the male owner protects his sister.,And I believe that when you go to school.,You must hate people who make small reports.,Especially boys who make small reports.,Girls also have it.,But it's not so obvious.。 ）

(I remember when I was in high school, there was a teacher's eyeliner in the class, I don't know if you have it, because my high school class is an art class, there are few boys, there are many girls, and the physical work is basically boys, and the head teacher is also very distressed about the boys, I have a sweet mouth, and I love to work, even if I hit the small report to my head, the head teacher didn't say anything about me, just told me to go to the office to talk, I was caught smoking or the head teacher protected me, and I didn't invite my parents.) ）
