Datang: Integrate three times the combat power of Lv Bu at the beginning

First Prize: Seven matching numbers, that is, six red balls and one blue ball have the same number.

Second Prize: Six red balls with the same number.

Third Prize: Five red balls and one blue ball with the same number.Fourth Prize: One blue ball with the same number. "

Wu Jue and Zheng Qian listened to Li Chengqian's explanation in a daze, frowning tightly.

"Is...is this difficult? Your Highness the Crown Prince..."

Wu Jue's face is full of doubts, no matter how she thinks about it, she feels that this is not a difficult task. With ten renminbi and one thousand gold, Datang has a population of tens of millions. If there are thousands of winners, then Qinghuo Trading Company will It's worth giving it to others.

"His Royal Highness, I think this is inappropriate. Once Qinghuo Gaming opens, the popularity can be imagined. But...but if there are too many first prize winners, it will be difficult if we can't afford it." gone."

Zheng Qian is also not optimistic about this project.

In fact, this is not to blame the two of them, after all, their computing power is not up to it.

What they don't know is that there are tens of millions of random arrangements for this simple 49 small wooden balls.

In other words, the probability of drawing the first prize is one in ten million.

This kind of winning probability cannot be said to be non-existent, it is almost equal to zero.

Of course, there will definitely be lucky people who are lucky enough to win the first prize, but the countless two pennies are enough to make Li Chengqian earn a lot of money.

Li Chengqian looked at the two of them, and said in a low voice: "Do you feel that this palace is someone who makes money-losing business?"

"Don't feel that the ten-cent money is too little, and don't feel that the first prize is too much. As long as you do what I say, I will guarantee that you will make a lot of money."

Wu Jue responded: "Although the ten coins are small, the Tang Dynasty has a large population and the attraction of gambling is great. There must be a lot of people who buy it. I'm not worried about income, but this... the number of people who won the lottery How to control..."

Wu Jue was still worried, but he knew Li Chengqian's bottom line, and he would never do anything fake.

Li Chengqian explained: "The probability of winning the lottery is not as high as you imagined. I tell you this, this first prize is not so easy to win."

Chapter 510 Green Fire Gambling

How can this be? " Zheng Qian lost his voice.

Although he trusted every word of Li Chengqian from the bottom of his heart, he couldn't believe it no matter what.

Although Wu Jue didn't speak, there was puzzlement in his eyes.

Li Chengqian didn't have time to explain to them now, so he said immediately: "This matter is settled like this, there is no need to discuss it any more, you follow my wishes and wait to see the result."

"For specific operational matters, I will draft a document, and you can follow the instructions on it."

Having said that, the two of them could only follow Li Chengqian's wishes.

Just as Zheng Qian was about to turn around and go out, he turned back and said, "Your Highness, what kind of material do we use to make this bill, and if it's an ordinary material, will someone imitate it to defraud the bonus?"

Li Chengqian picked up the cup and took a sip of tea, "Don't worry, I know it well, when the time comes, I will make a special batch of paper, and no one else can imitate it."

Today in the Tang Dynasty, only Li Chengqian has mastered the skilled paper making process. If Li Chengqian wants to make paper of several special materials, it is very easy.

Seven days later, Qinghuo Trading Company began to promote Qinghuo Gaming like crazy.

Fifteen days later, Qinghuo Gaming was officially launched.

As soon as the news that 1000 taels of gold was won with ten coins was sent out, thousands of people in Chang'an City were empty.

Due to the inconvenient transportation in Datang, the betting is sold and drawn separately by the Qinghuo firm in each city.

The Qinghuo lottery shops in Chang'an City were completely surrounded, crowded with traffic, and there was an endless stream of people queuing up to buy Qinghuo lottery tickets.

"You say, is this true? Why don't I believe it? If you buy a Qinghuo lottery ticket for ten cents, you will have a chance to get 1000 taels of gold. Is this Qinghuo firm crazy?"

"What do you know? People call it rich and powerful, and 1000 taels of gold is nothing to Qinghuo Trading Company."

"Don't worry about it, anyway, it only costs ten pennies. The two pennies are worth watching the excitement. If you can win the first prize, it will be a full 1000 taels of gold. Buy a big house and marry Wouldn't it be nice to have a few wives in the house."

People queuing up to buy Qinghuo lottery tickets were discussing in the queue.

Even if the flames are on fire today, it still hasn't lessened the interest of the common people.

Zheng Qian stood in front of the window on the second floor of the Qinghuo gaming shop, looking at the crowds of customers downstairs who lined up to buy lottery tickets, but there was no smile on his face.

Logically speaking, he should be happy that there were so many customers on the first day that the Qinghuo gaming shop opened.

But the consumption of two Wen per person did not make him happy.

It wasn't that Zheng Qian disliked the low amount of consumption, but he was worried about the 1000 taels and 500 taels of gold bonuses.

"Shopkeeper Zheng, go and rest. You have been standing here for a day, and you still need to eat something." The waiter at the side looked at Zheng Qian who looked like this and stepped forward to persuade him.

"Hey..." Zheng Qian let out a long breath, "Don't worry about me, you go down first, I won't feel at ease until I see the results of the first lottery."

Although Li Chengqian repeatedly explained, Zheng Qian's understanding of this thing still can't reach the level of Li Chengqian's answer.

Before the results of the first round of lottery came out, Zheng Qian couldn't rest assured.

Because Datang canceled the curfew.

The gaming firm is open 24 hours a day for five days, and after five days, there will be a lottery draw at the West City Square in Chang'an City.

It can be regarded as adding a little fun to the people of Chang'an City.

palace...

Ganlu Hall...

Li Shimin sat in the first place, eating cakes and tea, looked at Liu Renyuan who was beside him and said, "I heard that Qinghuo Trading Company has set up a... some kind of gaming company in Chang'an City, is there such a thing?"

Liu Renyuan nodded and said, "It is true. It is said that with two cents, you can get a grand prize of up to 100 taels of gold."

"When the people in Chang'an City heard about this, they all queued up to buy Qinghuo lottery tickets. After all, 100 taels of gold is not a small sum. Almost everyone will be moved when they hear it."

Li Shimin put down his cup, frowned, and thought: Can you get 100 taels of gold for ten Wen?Chengqian child is afraid that there is something wrong in his head.

Li Shimin asked suspiciously, "Then what does the Qinghuo lottery mean?"

Immediately afterwards, Liu Renyuan told him the rules of the game.

Li Shimin sat on the futon, listening with gusto.

Having lived in the deep palace for a long time, he is also full of curiosity about new things outside the palace.

After hearing the game rules of Qinghuo Gaming, Li Shimin couldn't help but click his tongue, "Chengqian, I don't know where he got these fancy intestines and a few small wooden balls. The city is empty of thousands of people."

"I just don't know what the chances of winning the first prize are, but with only these forty or so small wooden balls, the probability of winning the first prize shouldn't be too low."

Liu Renyuan echoed from the side: "Your Majesty, you are joking, what is His Highness the crown prince doing here? Besides, when did His Highness the Crown Prince ever do a loss-making business? According to General Yimo, this matter is not as it seems on the surface. Simple."

Li Shimin nodded and said: "That's right, Chengqian has the most ghost ideas. I heard that after the Qinghuo Trading Company undertook the road traffic improvement and underground drainage system projects, there were some problems in the company's capital turnover. This Qinghuo Gaming should make money for it." The project, logically speaking, will not lose money."

Immediately afterwards, Li Shimin looked at Liu Renyuan and said, "Have you ever bought a Qinghuo lottery ticket?"

He said with hope in his eyes.

"Hehe..." Liu Renyuan smiled awkwardly, "Your Majesty, you are joking again, how can I have time to join in the fun at the end?"

His voice just fell.

The old eunuch Chen Lin walked over and said with a smile: "Your Majesty, I asked someone to buy a Qinghuo lottery ticket from outside the palace. Originally, I wanted to surprise Your Majesty..."

As Chen Lin said, she took out a green fire lottery ticket with a golden edge from her sleeve, and handed it to Li Shimin.

Li Shimin scolded with a smile: "You old guy, you obviously bought this for yourself, but it happened to involve me, but if you take it out in time, I won't be as knowledgeable as you are."

"Hehe..." The old eunuch Chen Lin smiled awkwardly, "Thank you for your majesty's grace."

In fact, he really didn't buy this lottery ticket for Li Shimin, he bought one from outside the palace only out of curiosity.

Hearing that Li Shimin is also interested, he, an old eunuch, should offer it with both hands.

Holding the Qinghuo lottery ticket, Li Shimin couldn't help but click his tongue when he saw the exquisite patterns and numbers printed on the paper. The materials alone cost more than ten cents.

He really didn't know what Li Chengqian used to make money.

In fact, up to now, Li Shimin still doesn't know the terrible efficiency of industrial production.

Under the production efficiency of industry, the cost of some things is negligible.

Chapter 511 Excited Li Chunfeng

Li Shimin held the green fire lottery ticket in his hand and looked at it to himself.

lean less...

He raised his head and said to Liu Renyuan: "Go and find Li Chunfeng for me. Today I want to see what the chances of winning the first prize in this lottery are."

Li Shimin feels that the connection between these seven numbers and 49 wooden balls is not so simple.

According to Li Chengqian's character, this business will definitely not lose money.

It is not so simple to use ten Wen to win 100 taels of gold.

"It's Your Majesty, the last general will go now."

Liu Renyuan agreed and left the hall.

In just a moment, he brought Li Chunfeng over.

Li Chunfeng, a famous mathematician in the Tang Dynasty, served in the Taishi Bureau.

He has made outstanding achievements in the fields of astronomy, mathematics, Yixue, astronomy, calendar and calculation.

Li Chunfeng is the first person in the world to grade wind.

His masterpiece "Yisi Zhan" is the earliest monograph in the history of world meteorology.

"Wei Chen, see Your Majesty."

Li Chunfeng walked into the room, stepped forward and saluted.

Li Shimin waved his hand and said: "Chunfeng is free of courtesy, I have called you here because I need you to do something."

Li Chunfeng responded: "Your Majesty ordered it, and I will do my best."

"This is a thing called Qinghuo lottery sold by Qinghuo Trading Company. Six balls are taken in turn from 33 wooden balls, and one wooden ball is taken from [-] wooden balls. These seven balls are the selected ones. sequence of numbers."

"I want to know what are the chances of me picking the exact number."

Li Shimin handed the lottery ticket to Li Chunfeng while explaining the rules to him.

"This..." Li Chunfeng frowned, "Your Majesty, it's really difficult to rely on thinking alone. I wonder if Your Majesty can allow me to do some calculations on the spot."

Li Chunfeng's love for mathematics has reached the point of obsession.

Now Li Shimin actually gave him such an interesting math problem, which instantly aroused Li Chunfeng's desire to calculate.

"Okay, I agree."

"Returning to Your Majesty, the calculation tools of the minister are still in the Taishi Museum, please come as soon as you go."

Soon...

Li Chunfeng came to Ganlu Palace with calculation tools and a thick stack of paper.

He wrote down the game rules of the Qinghuo lottery on paper, and began to calculate on the copybook.

Such an exquisite math problem aroused Li Chunfeng's fighting spirit.

On the battlefield of this math problem, he is the general who charges forward.

Li Shimin sometimes played with the lottery ticket in his hand, and sometimes walked up to him, watching the serious and meticulous Li Chunfeng practice math problems.

During this period, Arabic numerals had not been introduced into the Tang Dynasty, and the numbers were all pictographs, so it was much more difficult to do math problems.

Li Chunfeng leaned over the copy, immersed in this question, sometimes happy, sometimes frowning.

Time passed by like this minute by minute, but Li Chunfeng was still immersed in his own world.

He has never discovered that there are such ingenious mathematical games in the world.

At the same time, he was curious about the person who invented this mathematical game.

In the field of mathematics, Li Chunfeng has never convinced anyone in his life, but this time he has met his opponent.

Sitting in front of the royal case, Li Shimin had already eaten a whole plate of pastries and drank a pot of tea.

"How about Chunfeng, haven't you calculated the chance of winning the first prize?" Li Shimin asked Li Chunfeng.

But Li Chunfeng was so immersed in it that he didn't hear what Li Shimin said at all.
