Chapter 117: Criminal Psychology Profiling and Probability

There are three denominations of one thousand, sixteen and four hundred thousand prizes left.

Yunjin, who has never bought lottery tickets, is a little excited, won't really win!

Then Wei Xiao still started scraping from the lowest 1,000, and she scraped a row of numbers with her hands neatly, and missed...

Yunjin felt understandable, and then one thousand six scraped it open, and still didn't hit...

Yun Jin felt that his heart was starting to pound, he wouldn't really hit 400,000!

And then... 400,000, still missing.

Brocade:...

He looked at Wei Xiao with a look of suspicion on his face. This girl can't be bluffing him, saying that she is the king, but in fact she is just a bronze.

But Xiao didn't care at all, and the expression on his face didn't even make waves.

She quietly put the first ticket aside and picked up the second.

The second lottery ticket, but Xiao also started to scratch the amount first, Yun Jin didn't pay much attention this time, he played with his mobile phone, and glanced at it with his spare eyes, the denomination is not large.

Then Wei Xiao "brushed and brushed" and scraped, the action looked really exciting, which made Yun Jin feel a little itchy and wanted to scrape.

This thing seems to have a wonderful magic.

The second one still missed.

Yun Jin completely believes that Wei Xiao is just a bronze. He silently felt sorry for this child in his heart, and finally earned a few hundred yuan, and as a result, he contributed to the country, which is really pitiful.

While thinking about it, Yun Jin was brushing the news, since he was hit by the old naughty boy last time, he also developed the habit of watching the news, after all, even an old man knows more about current affairs than himself, which is indeed a bit embarrassing.

Yun Jin didn't want to be dissed by the old naughty boy and say that he was out.

He swiped the news and found that in an inconspicuous location, there was a local news that there was a university student, and the dormitory members went out in a group in the middle of the night, and the result was that they disappeared collectively, and the classmates in their class found that they had been absent from school collectively for several days, only to realize that something was wrong.

They contacted their family and friends, but they didn't see them, and then called the police, and the police looked up the surveillance and found that they had disappeared as they passed through an alley.

Because there was no surveillance in that alley, it was not clear exactly what was going on.

But the road surveillance at the entrance of the alley clearly captured the image of them entering. The road surveillance at the exit of the alley did not capture the image of them coming out.

Yun Jin looked at the location of the report, and it was Qingshan Road, which was not far from their community.

Yun Jin couldn't help but think, could it be that the moss was dry?

But it shouldn't be, no matter how good the moss is, do you still have the ability to turn people into nothing?

Yun Jin thought as he inadvertently glanced at the table, but Xiao was already scratching the last few sheets.

She split the scratch music she had previously scratched into two stacks.

There were five sheets in one stack, and the other was thick, Yun Jin picked it up casually, counted it, sixteen.

He looked at it and found that none of the winners in this stack had won the prize, and the other stack had won the lottery.

Twenty-one, five in the middle, this probability is okay? Yunjin has no concept.

Wei Xiao quickly scraped the next three, and then put them on another stack together.

Yun Jin was stunned, isn't the probability of winning three cards in a row a bit small? Could it be that he didn't win the lottery in this stack, and he didn't win the lottery in the other stack?

But Xiao didn't care what Yun Jin thought, picked up the stack of scratch tickets and looked at them one by one, after reading it, she put it on the table and stretched out her hand to Yun Jin, Yun Jin put her own stack in her hand, she picked it up, and looked at it one by one again.

Yun Jin guessed that she was probably checking if there was anything missing, and this kid was really careful.

After Wei Xiao finished checking, Yun Jin asked, "What's the matter?"

Wei Xiao nodded.

Yun Jin comforted, "It's okay, don't buy it next time if you don't return to the capital, buying this is IQ..."

Halfway through speaking, Yun Jin suddenly froze, because he remembered that Wei Xiao nodded, not shook his head, and he looked at Wei Xiao with a surprised expression, "Back to basics?"

Wei Xiao nodded again, and then casually handed the few stacks to Yun Jin.

Yun Jin took it and looked at it carefully. Ten dollars were won in the first one, ten in the second, five in the third, fifty in the fourth, three in the fifth, and a hundred in the sixth.

Yun Jin calculated in his heart, this is one hundred and seventy-eight, and there is still a gap of fifty yuan.

Then he picked up the last one, compared the numbers one by one, and half-ringed, he raised his head in surprise: one thousand!

The last scratch ticket actually won a thousand!

I'm going! It's really profitable.

Yun Jin took a closer look again, it was true, and this one alone was back to basics.

Wei Xiao put in two hundred and thirty-three, and won one thousand one hundred and seventy-eight, which was five times greater.

But after thinking about it, Yun Jin knew that this was actually luck.

Criminal psychology profiling actually covers a part of probability, and seriously speaking, criminal psychology is to judge some characteristics of the murderer through probability.

So when used in scratch, Yunjin doesn't use a pen, and he knows the result by mental arithmetic.

There are a total of 23 tickets, and 8 of them win, and the probability of winning is 35%.

The winning amount actually fluctuates between 3 and 100, and the value of the winning ticket is 30 after removing the extreme values, 3 and 1000.

Therefore, in fact, the reason why Wei Xiao returned to his original cost was because she won 1000 fast in the last one, otherwise she would probably lose money.

Thinking of this, Yun Jin was happy to scratch it, he returned the lottery ticket to Wei Xiao and explained it to her.

Wei Xiao nodded, indicating that he listened, but he would still buy lottery tickets... Because she also has her own unique cheats.

Yunjin said that the most tiring thing in this life is to communicate with women.

Anyway, this is Wei Xiao's own money, so he doesn't bother to care. After all, even if she didn't have money, Yun Jin wouldn't starve her.

Wei Xiao put away the lottery ticket, then wiped the table, and Kou Bo teleported to the two of them.

It was wearing a newly bought chef's suit and a chef's hat, and it felt more handsome than the paper paste in the morning.

Uncle Kou bowed slightly, and said weakly, "Yun, Doctor Yun, assistant, assistant, dinner is ready." ”

"What did you do tonight?" Yun Jin asked.

Uncle Kou smiled shyly, and actually made a joke, "Secret, secret." ”

Yun Jin smiled, "Then let's serve the food." ”

As soon as he finished speaking, Kou Bo snapped his fingers three times, and three dishes with bowls appeared on the table.

Brocade:...

Seeing this scene again, Yun Jin always has a lingering shadow, a sense of foreboding...

He glanced at Wei Xiao, but Wei Xiao still couldn't see any expression, just looked at the dish calmly.

Yun Jin was really curious, wasn't she worried?

Wei Xiao seemed to hear Yun Jin's heart, she turned her head and glanced at Yun Jin, "I don't like expressionlessness, I haven't learned to control the expression of my face yet." ”

This is a very fresh and unconventional reason...
