The noisy crowd suddenly calmed down, and everyone stared at the man in the middle.

Jing Hao, who was about to leave, saw that everyone suddenly calmed down. He couldn't help being curious and took his husband back to the crowd to see what happened.

One of them seems to be a waiter, who has been explaining and groveling in front of an old man, looking very helpless.

After squeezing into the crowd, Jinghao looked at the waiter who had been asking the old man to rest. Don't make trouble here, but the old man seemed to be very tough and stood in the middle.

Ye Tanmo couldn't help frowning when he saw a man leaning on the old and selling the old in the middle. After all, this method was thought out by Jing Hao. Naturally, he didn't like anyone to make any mistakes in the middle.

Walking into the crowd, Jinghao asked the waiter what happened? How can you make an old man so angry.

The waiter's attitude is very good. Although he doesn't know Jing Hao and hasn't seen the "childe" in front of him, he is also an honest gift.

Some people who have finished shopping also take their own stations nearby, while those who have not bought anything have been watching and can't help whispering.

The waiter said, "you don't know. The old gentleman insisted that all the awards we set up were fake. He saw it from sitting here. Now he said that he only saw the third prize and participation prize, but didn't see the first and second prizes, so he thought we didn't set up such awards at all, just to deceive them."

I didn't expect that the old man made trouble for this matter. Jinghao really felt incredible. It would be nice to give them small gifts. Even if they didn't set awards, it's understandable. Why did they provoke so many irrelevant rights and wrongs.

After hearing the waiter's explanation, the people nearby couldn't help talking. After all, dozens of people have drawn prizes from morning to night, but there has never been a first or second prize.

Jinghao pointed to the award note next to him and said, "it has been clearly written on it. As long as it is a lucky draw, all will not be free. But our car shop is also a commercial organization. Since business is naturally profit-based, we hope to attract more customers with high quality and low price. But it can't be said that it's to satisfy you, but that the whole car shop is in a deficit. In that case, our car shop can't continue to operate, and naturally you can't buy a car. "

One of them stood up and asked Jinghao whether he was the boss behind the car shop.

The waiter was also a little surprised. He had never seen the childe, but he really didn't know who the boss behind the scenes was.

He shook his head and Jinghao said that he was not the boss behind the scenes of the car shop, but just helped manage it temporarily.

After all, most people only know that this journey of wealth appears out of thin air and do not know what the origin is. Even if they clearly know where the village and car factory are, they do not know the boss behind the scenes. Therefore, it is understandable that they are worried about the quality of things.

Jinghao said to the old man, "we have also made it clear that there are 200 lucky draw places, but there are only three first prizes and ten second prizes. All the rest are third prizes and participation prizes. Under such a probability, even if no one has won the first and second prizes now, someone will win them in the future, If you don't mind, you can go here after the 200th customer draws the prize. If there is still no first or second prize, we will naturally make self-criticism on this matter. "

Is it just criticism? The old man seems to be unwilling to give in.

He smiled and said quietly, "even if we don't criticize, what can you do to me? The reason why we make self reflection is that we want to apologize to these real customers, rather than give in to people like you who make trouble out of thin air. And I made all the awards myself. There will be no problem. "

Hearing the man's voice in front of him, the old man couldn't help but be suspicious and began to think of other ways.

At the side of Ye Tan Mo, looking at the old man, he always felt that he wanted to get some benefits from it.

Jinghao is also a little strange. The old man's intention is very strange. After all, if he just wants to confirm whether there are first and second prizes in it, he should be very happy when he gets his own guarantee, but now he seems very embarrassed. It seems that he imagines those who want to cheat some money from these stores when they see that the new stores have just opened.

Before long, the old man said, "at the beginning, maybe three out of 200 people want to win the first prize, but these people have finished, and the rest will become three out of 100, or 50 or even 30. That's less. Isn't that unfair to the people in front? "

Unexpectedly, the old man would say so. Jinghao really wants him to learn the statistical probability in mathematics.

When the people nearby heard these words, they couldn't help guessing. What the old man said is really reasonable.

Jinghao said, "no matter who wants to draw a first prize from this box, the probability is three out of two hundred. There can never be any injustice. Whether you are first or last, this is the most basic probability problem."

After all, in ancient times, when no one even paid attention to mathematics, how could there be the so-called probability analysis? Everyone didn't believe it and couldn't help asking the car store to give an explanation.

When everyone was making trouble, Jinghao directly stood on the stool and questioned everyone. If they were willing to draw the last prize, what would they do if someone in front took away the first and second prizes?

This seems to make sense. Everyone couldn't help looking at each other.

Ye Tanmo pulled Jinghao down directly. She didn't know when she ran directly to the stool. It looked majestic. What if she accidentally fell?

In fact, Jinghao has some regrets. First, he regrets that he didn't use the turntable. Anyway, he can carry out this lucky draw with different sizes of each grid. In this way, everyone won't feel unfair; Second, I regret that I didn't learn the content of mathematical statistics well. I basically forgot it when I studied medicine, otherwise I won't even explain it clearly now.

Just at this time, a man pointed to the old man and said, "he asked me for money when he bought my steamed stuffed bun. I didn't give it to him. He had to say that my steamed stuffed bun was not delicious in front of everyone. As a result, I was scolded by everyone on the first day of business. But now everyone says that my steamed stuffed bun is delicious. He is a liar. Don't listen to him. "

The people who were still suspicious began to change their words and accuse the old man.
