As soon as Qin Chuan arrived in the class, Chen Lin approached her, "Qin Chuan, do you know the ranking dispute?"

"What ranking?"

Qin Chuan was confused.

"That's right now, everyone is betting on who is the first place in this monthly exam, who is the second place, who is the third place, who is the fourth place, and who is the fifth place."

"Who did this?"

Qin Chuan asked in surprise: "Will the school agree?"

"Of course the school does not agree. It is sneaky. It seems that Lu Hanyu did it. He said that he guessed the first, second and third, and he could have 10,000 yuan, and the top five, and he could have 20,000 yuan. He could have 500 yuan to participate."

Chen Lin said.

"You want to participate?"

Qin Chuan frowned slightly.

"As long as I refer to the situation of the last exam, I think the top five is easy to guess. If the top three is not necessarily the case, I can only buy the top five."

Chen Lin said.

"In fact, it's not easy. The top ten people are capable. During the exam, there are some luck elements. It's hard to guess the top three in the class. Moreover, if there are two key classes, the chances are even more difficult."

"Five hundred, 20,000, I think it's worth it. Choose 5 out of the top ten people, and this kind of chance is very high, I want to try it.

Give me some reference."

Chen Lin said.

"Then you buy the top five before, but there will be a problem. This time it was organized by Lu Hanyu. In other words, after he was in his hands, he could deliberately get the fifth place. I think the chance of winning is very few. You have to know that if everyone guessed, wouldn't he have to pay death?"

Qin Chuan suggested.

"I'll try it. The exam is about to end. I'll buy the top five. The top five before the exam is over. It's difficult to win the top three, but it's still easy to choose five out of ten. When I plant it, I'll treat you to a meal.

I'll buy it first."

Chen Lin said.

Qin Chuan continued to review English.

"Wow, Qin Chuan, guess how many people participated?"

After Chen Lin entered the group, he asked Qin Chuan.

Qin Chuan thought for a while, "We have eight classes in total, won't there be three hundred, right?"

"There are more than 500 people now."

Chen Lin said.

Qin Chuan looked at Chen Lin in surprise, "Why are there so many people?"

"It's not our grade-one, but some people also participated in the freshman year and sophomore year."

Chen Lin is a ruthless person, "Five hundred yuan per person, five hundred yuan is 250,000 yuan. If 500 people are planted, Lu Hanyu will lose to death."

Qin Chuan looked at Lu Hanyu.

Lu Hanyu was very calm and calm.

"Who did you buy?"

Qin Chuan asked.

"You, Gu Yan, Lu Hanyu, and two others are from Class 2, which are the first five before."

Chen Lin said with a smile.

"If I were you, I would buy the first six in the past and remove Lu Hanyu."

Qin Chuan said.

“Really or not?

You think Lu Hanyu deliberately failed to get into the top five. No, he wouldn't have deliberately failed to get into the top five for the sake of this 250,000."

"I don't know if he will do poorly, but it is still easy to get the top five on purpose. In fact, it is also dangerous for you to buy the top six, because there are really many possible arrangements, unless you count the following arrangements except Lu Hanyu."

"Ten thousand yuan, 20 yuan, 500 yuan, 20 algorithms, just earn a few hundred yuan, it doesn't make sense, right?"

Chen Lin said.

"You're counting less. If Gu Yan and I are fixed and removing Lu Hanyu, it's equivalent to selecting 3 people from the remaining 7 people. How many arrangements are there?"

Chen Lin immediately took out the pen and calculated it.

“I’ll go, 210 kinds.

so much."

Chen Lin was shocked.

“And maybe there will be a dark horse.

That's even more likely. You think it's really difficult to choose 5 out of ten people."

Qin Chuan said.

Chen Lin cried sadly, "I think my five hundred yuan has been wasted, what should I do?"

"There is another kind of thing, that is, you go to Class 2 and ask the people you know who they chose?"

"Why?"

Chen Lin said inexplicably.

"Their answers will help you remove many kinds of impossible answers. They often get along with classmates. In fact, it can be seen that those who have better grades are, at least, can help you remove possible answers."

"I'll go right away, I'll buy a few more, otherwise my money will be wasted."

Chen Lin went out.

Qin Chuan pulled her hand out, "There are still many possibilities. What if Lu Hanyu still relied on the top five?

So, you may buy a few more arrangements and then rinse it with water.”

"I'll go and ask first, wait for me."

After a while, Chen Lin came back, "I asked, and they said that most of the top five they bought were Qin Kechu, Gu Yan, Lu Hanyu, Chen Bin, Sang Xue, I thought about it, you, Gu Yan, and then Chen Bin, Shang Xue, Qin Kechu. Will this probability be much higher?"

“It’s theoretically.”

Qin Chuan said.

"Did you buy it?"

Chen Lin asked, wanting Qin Chuan to buy it with him.

She felt that if Qin Chuan bought it, she would feel at ease.

Qin Chuan shook his head, "The chance of winning this kind of prize is too small, and five hundred yuan is not a small amount."

"But if you win, you can get 10,000 yuan."

Chen Lin encouraged him.

"Don't look at that ten thousand, it's not that good."

"We each pay two hundred and five. I don't have that much money anymore. If we plant it, we will be five thousand each. I don't buy it. I feel unwilling to accept it. If I lose, I will be willing to do so. Please, Qin Chuan, please, Qin Chuan."

"You have to think about it, because there are many possibilities."

"I know, 10,000 is not that easy to get, but this probability is very high, I want to give it a try."

"You know the game console, the kind of coin-operated ones, you just look at the gold coins and then invest more money. In fact, it is designed to give you this kind of hope, but it is actually very difficult to win."

"I know, I just want to try it. Qin Chuan please, please."

Qin Chuan saw that she wanted it so much, "I, Gu Yan, Qin Kechu, probably in the top five, and..."                                                                                                                 

Chen Lin saw the teacher come in with the test paper.

Qin Chuan transferred the money to Chen Lin.

She studied the list and bought two copies.

The teacher started to hand over the test papers. After buying them, she put away her phone and started the exam.

Fortunately, she has done a lot of English questions this time, and she knows them all.

Soon she finished the work, checked the side, handed in the paper, and went out.

The next class is mathematics, and she doesn't need to review anything. After the exam, she goes to the playground. She wants to exercise a little, but she has not exercised for a long time. In fact, it is not good for her health. Moreover, she knows that she has lost her physical condition recently.
