Li Yincheng turned the menu to Ran Jing, "What does senior sister like to eat?" Let's order first! Ran Jing handed the menu to Gu Luobei again, but Gu Luobei unceremoniously took the menu and flipped it up.

Gu Luobei spoke while flipping through the menu, "Let's order a stir-fried bitter gourd first, bitter gourd can beautify and nourish the skin, oops, I'm also confused, Senior Sister Ran has such good skin, how can I rely on bitter gourd to raise it" This thief can speak in the vernacular, and he amused these two female graduate students with his food. The focus of his conversation was on Ran Jing, it seemed that he had some thoughts about Ran Jing, but he didn't snub Liu Yue, and if he said three or five sentences to Ran Jing, one sentence would be with Liu Yue, for Li Yincheng and Zhao Zhe, it was just an occasional conversation, and after a while, he ordered six dishes and one soup.

Ran Jing hurriedly said, "Enough is enough, I can't finish eating now." ”

Gu Luobei waved his hand to the waiter when he heard Ran Jing's words, "Okay, that's all, and then a dozen beers, Zhao Zhe, can you two have a bar?" Do the two seniors drink juice or Sprite? ”

Ran Jing and Liu Yue finally ordered two cans of Lulu, and when Gu Luobei saw this, he immediately ordered the waiter, "Lulu should be hot, cold is not delicious." ”

The meal was served after a while, Gu Luobei took Lulu first, wiped the can with a paper towel, then opened it and handed it to Ran Jing and Liu Yue, and then filled Li Yincheng and Zhao Zhe's wine glasses with beer.

Before eating, Gu Luobei raised his wine glass, "Come, let's do one first, I wish the two senior sisters younger and more beautiful." ”

After drinking, Li Yincheng glanced at Zhao Zhe, are you here to help or to pick up girls? Zhao Zhe shrugged his shoulders and expressed helplessness.

Fortunately, Gu Luobei can still remember what the dinner was for tonight, and when he was halfway through eating, he finally remembered to help them solve the problem, "Two senior sisters, what about my fellow countryman and his roommate, he was very strict in high school, and he really can't handle this piece of high mathematics, so the two senior sisters will help me find a way." ”

Li Yincheng nodded hurriedly, "I'm stupid, I can still deal with the past by rote memorization of liberal arts, but I can't do anything about mathematics; I'm not as smart as my seniors, so I can't figure it out. ”

Zhao Zhe also followed by good words and pretended to be pitiful, "Senior sister help, if you can't pass this time, there will be no hope for the make-up exam in the future, and you can't pass the exam until you get a graduation certificate and a degree certificate, how can you find a job in the future." ”

Ran Jing hesitated for a while and didn't speak, and Liu Yue asked rhetorically, "Don't you two usually do your homework, except that the mathematical symbols are a little ugly, which proves that the reasoning process is quite slippery?" ”

The two of them smiled awkwardly, "Hehe, we don't know math at all, but we can't afford not to hand in homework, and then there happens to be a roommate in the dormitory who is good at math, and then you understand." ”

"Copy your homework, copy your homework, hide what you're doing, as if others didn't copy it, I dare to say that at least thirty percent of the students in your class copy their high math homework." Liu Yue said with a big grin.

Gu Luobei looked at their embarrassed appearance, and gently pushed Ran Jing's arm, Ran Jing raised her hand to stop Liu Yue's words, "Alas, forget it, who hasn't learned anything yet, haven't you passed English level 6 yet?" ”

When Liu Yue heard the topic of the sixth grade, he leaned on the table with his right hand on his forehead, "Can we not talk about this topic, there are only five people in the class now, you can help me find a way." ”

Maybe it's because of the same disease, Liu Yue is not as disgusted with them as he was at the beginning; Coupled with Gu Luobei's mobilization of the atmosphere beside him, Liu Yue finally relaxed a little. "How many points can you two get on the test on your own?"

Li Yincheng can see that Ran Jing is a person who doesn't like to talk and has no opinions, as long as she convinces Liu Yue to help, she basically has no problem, as for how many points she can get in the exam, Li Yincheng was depressed again, "Senior sister, how are the test papers of our exam arranged?" How many multiple-choice questions are there? How many points? ”

Liu Yue thought for a while, "Last year's test paper seemed to be four multiple-choice questions, one ten, then two calculation questions, one ten, two proof questions, one ten, and the last big question twenty points; This year's story should not be much different from last year. ”

Li Yincheng calculated slightly, "I guess I can get a multiple-choice question, and the four multiple-choice questions can probably get ten points according to the one-quarter correct probability, right?" As for the calculation questions and proof questions, I don't think I can even understand the questions, let alone do them! I don't even have the courage to look at it. ”

Zhao Zhe also agreed, "I guess it's about the same, every time I copy my homework, I look at other people's homework like learning calligraphy, as for what the content on it means, I don't understand it at all." ”

Liu Yue took a sip of Lulu, and then shook the can, Li Yincheng saw this and hurriedly pushed open the door and shouted outside, "The waiter will bring another can of Lulu, no, two cans of Lulu, it needs to be hot." ”

"Thank you!" Liu Yue first thanked Li Yincheng, and then complained mercilessly, "Hey, it looks like a clever child, why is math so bad?" Let me correct you a mistake first, each multiple-choice question has four answers, and the probability of being correct is one in four, which is true, but it does not mean that you can get one of the four multiple-choice questions right; This probability should be calculated like this, multiply the accuracy of one of the four by one of the four and multiply it by the three of one minus a quarter, the combination of one of the four is equal to the factorial of four divided by the factorial of four minus one, the answer is four, the cubic of one minus a quarter is equal to twenty-seven of sixty-four, then four times a quarter and then multiplied by twenty-seven of sixty-four is the probability that your four questions are correct, this probability is twenty-seven in sixty-four, and when converted into percentages, it is about forty-two percent, not even half! Looks like the two of you are really bad at math. After finishing speaking, Liu Yue shook his head.

This calculation stunned Li Yincheng and Zhao Zhe, they looked at Gu Luobei and Ran Jing with blank eyes, Gu Luobei first applauded to express his appreciation for Liu Yue's excellent calculation ability, and then said, "Senior sister is right, it all depends on Meng's words, and the probability of Meng's four multiple-choice questions is indeed less than half." ”

"It seems that we didn't even have ten lives?" The two looked at each other and smiled bitterly.

"Haha, you can't say that, maybe you two are all lucky? I've calculated that the probability of the four realms being all right is 1 in 256, so you two can try your luck as you have. Liu Yue gloated and laughed at them.

At this time, Ran Jing couldn't stand it anymore, "Sister Yue, don't laugh at others; Think of a way you can help them. ”

Liu Yue took a chopstick sour soup and swallowed it slowly before saying, "Okay, okay, don't tease you two, in fact, it's not impossible, the homework in your class was changed by the two of us before, and the test papers of the exam were probably changed by the two of us, and the scores were also calculated by the two of us, so I want to figure out a way when the time comes." ”

Li Yincheng and Zhao Zhe were overjoyed, "Then thank you first, senior sister, we will do this cup first." The two stood up and toasted Ran Jing and Liu Yue, and they took a sip in response.

Putting down Lulu, Liu Yue spoke again, "But don't pin all your hopes on the two of us, the test paper is vague, and it will be opened after it is changed, if we don't recognize your test paper, it will be difficult to change the score after grading." ”

"Senior sister, if we don't draw an ink pimple to make a mark on the first big question, you will know that this is our test paper when you see the mark, and when you change the paper, just give a little bit and pass." Zhao Zhe came up with an idea.

Liu Yue nodded, "Okay, this method is okay; But say it in advance.,When the time comes, I'll give you a maximum of 40 points.,The usual attendance points are handed in every time you two do your homework.、If you don't get caught, it's a full score of 20.,Add it up to just pass.,I won't give it any more.。 ”

"That's for sure, sixty points is enough for both of us; I'm embarrassed to cheat if I can't pass the exam, so I still have the face to get a high score, and we just want to pass, not to get a scholarship. Li Yincheng hurriedly said that he was very satisfied as long as he passed.

"Okay, then this matter is decided, just give you both a passing grade when the time comes."

A lot of tricks have come out in this chapter. At six o'clock in the evening, I will add another chapter, and ask for collection.
