Fang Yaoyi pondered for a moment and said, "I haven't seen the account book, but if it is based on all the numbers, the number in the first place is one, and it should be about one percent. ”

Qin Shou nodded and said, "If it is according to the expected expectations, what Miss Fang said is very right. ”

"But that's not the case."

"After analyzing the data obtained from a pile of actual life accounts, it is concluded that the probability of the first digit being one is about 30% of the total, that is, 3 out of 9, which is far more than what Miss Fang said."

"Conversely, the higher the first digit, the smaller the probability of occurrence."

"I wonder if you can understand that?"

Fang Yaoyi blurted out: "How can this be? ”

Seeing Fang Yaoyi's expression, Qin Shou was not surprised, smiled and said, "At first, I didn't believe it like you, but that's the case. ”

As he spoke, Qin Shou called out to the people in the mansion and ordered: "You go to the wine shop for a run, and you will come to the wine shop with the fan to come to the account book of the wine shop." ”

Qin Shou continued: "Miss Fang, in fact, many things should be like this in our conventional subconscious cognition. ”

"But if you do it in the field, you will find that there will be a completely different answer."

"For example, if two stones, one large and one small, fall from the same height at a very high height, which do you think will land first?"

Fang Yaoyi didn't think about it, "It should be a big stone." ”

Qin Shou smiled and said, "It's landing at the same time." ”

Fang Yaoyi looked at Qin Shou in a daze, and only held back a sentence for a long time, "Childe, don't laugh." ”

Qin Shou did not refute it, as he said, some things will feel like they are talking about it in conventional cognition, but in fact they are the real truth.

Just as he was skeptical at first.

After the test of having nothing to do, I believe it.

This is a science that was not known in ancient times.

The same is true of Benford's law.

Benford's law, also known as the law of the first number.

In the present life of Qin Shou's life, it is often used in the economic field, and through Ben Fu's law, it can be screened for digital fraud, and it is also the place where the false financial reports of listed companies in later generations are often planted.

This law may seem unrealistic and contrary to human intuition, but it does exist and has been verified many times in later generations.

So you see, science is sometimes so unreasonable, unintuitive.

After hearing this, Fang Yaoyi was still a little incredulous.

Qin Shou ordered some food with chopsticks and said, "Let's eat first, when the account book arrives, I'll show you it clearly." ”

Finish breakfast.

For some reason, the people in the house have not returned.

Qin Shou thought for a while and said, "At this time, why don't I come and test the truth of the stone for Miss Fang." ”

With that, Qin Shou walked out of the main hall and found a higher pavilion, holding two stones, one large and one small, in his hand.

The two of them found the stairs again and went up to the roof.

Qin Shou stood on the edge of the eaves with a stone and said, "Miss Fang, stay away and watch carefully." Fang Yaoyi looked at Qin Shou with some concern and said, "Son, be careful." ”

At this time, Su Xiaofan happened to run in in a panic with the account book, and when he saw Qin Shou standing on the roof, he was immediately frightened.

"Auntie, what are you doing, what can't you think of!"

"Miss, why don't you persuade your uncle!"

Fang Yaoyi and Qin Shou were both amused by the little girl's appearance, and Fang Yaoyi said, "Fan'er, don't ask for it."

"Li Gongzi and I are trying."

Su Xiaofan tilted his head and wondered, "What kind of attempt?" ”

Fang Yaoyi smiled: "Fan'er, do you think the big stone and the small stone are thrown together, which one will land first?" Su Xiaofan stared at Fang Yaoyi with big eyes, as if looking at a fool, "Of course it's a big stone!" Fang Yaoyi pointed at Qin Shou and said, "Xiao Li Gongzi said that these two stones will fall to the ground at the same time. Su Xiaofan sighed, nodded and said, "That's the one that landed at the same time." ”

Fang Yaoyi: "??? ”

It seems that it is necessary to have a long talk with Fan'er, how can this be completely blindly believed by Xiao Li Gongzi.

Although I sometimes believe in Xiao Li Gongzi, this is obviously impossible.

Wait for the two to keep a safe distance.

Qin Shou let go of his hand.

— times.

Twice.

Three times.

Fang Yaoyi's eyes widened.

I can't help but feel a little scary.

"Oh my God, it's really landed together, so it seems that the account is also true!"

Su Xiaofan was puzzled: "Miss, what are you talking about?" ”

Fang Yaoyi shook her head slightly and said, "It's okay." ”

At this time, Qin Shou also slowly came down from the roof.

"Fan'er, why did you come here with the ledger?"

Su Xiaofan said seriously: "I'm afraid that this person is a liar, so I came over with the account book myself." Qin Shou helplessly stroked his forehead, this fan, if it is really a liar, you are not afraid that you will also be deceived. However, Su Xiaofan's heart is good, Qin Shou took the account book and said with a smile: "Thank you, Fan'er." With that, he took the two of them directly to the main hall.

"―Five taels ......"

"Thirty-Nine ......"

"One, two, five, ......"

According to the data on the ledger, count them one by one.

Fang Yaoyi's beautiful eyes trembled slightly, and sure enough, it was not much different from what Xiao Li Gongzi said. The first digit is one, and it really accounts for 30% of the total.

Fang Yaoyi glanced at Qin Shou with a complicated gaze, "Little Li Gongzi." ”

"You... It's just as wise as a demon. ”

Qin Shou's schemes again and again opened Fang Yaoyi's eyes, and there were many ways that she had never heard of.

When Qin Shou heard this, he smiled lightly, and said in his heart, I am not a wise demon.

Rather, it is a dimensionality reduction strike from the future.

Late at night.

Fang Xuanling dragged his tired body back to the house, his eyes were red, and he was obviously extremely tired.

He also participated in the work of taking inventory.

Fang Yaoyi had been waiting for a long time, and when she saw her father's appearance, she was also distressed, and hurriedly made a cup of tea, "Daddy, how is the work of the household department taking inventory today?" ”

Fang Xuanling sighed, and said helplessly: "There is little progress, and the remaining account books are piled up. ”

"Where's Nini's little girl? Have you been learning well lately? Because of her recent affairs, Fang Yaoyi didn't have time to take care of Nini's studies, so she simply hired a gentleman to teach Nini.

Fang Yaoyi replied: "Mr. said that Nini is very smart, a quick learner, and very well-behaved. ”

"It's just that when I'm free, I always want to pester to find Xiao Li Gongzi."

Fang Xuanling nodded, suddenly remembered what he remembered, and asked, "After you get married, I'm afraid that Nini will also be entangled in the past." ”

As he spoke, Fang Xuanling's tone was a little lost.

That's right.

Fang Xuanling has three sons, all of whom have already married and are officials outside, and they can't come back a few times a year.
