Text: Chapter 151 Mathematical Models
Buying the Chinese team to lose is patriotic!? Yang's question made almost everyone present hesitate and find it difficult to answer.
"Caishen, you didn't make a big bet to buy the Chinese team's loss for patriotism, right?" Old Song Yin and Yang asked Wu Bi strangely.
Wu Bi grinned and said: "I bought the Chinese team to lose because it would lose." ”
"What do you mean by that?" The small odds asked, "Caishen, do you really have any inside information?" ”
Wu Bi smiled again and said: "There is no inside information, I just listen to the guidance of the masters." ”
When Lao Song heard this, he suddenly came to his senses and asked, "What kind of master?" Can you also introduce me to him? ”
"Alas!" The small odds glanced at Lao Song and said, "Isn't Caishen a master now?" ”
"Oh! Yeah! It's because I have eyes and don't know Tarzan. Lao Song hurriedly set up a round for himself.
"Don't dare to be! Don't dare to be! Wu Bi waved his hand, but there was an arrogant smile on his face, and he said in a low tone, "Actually, I have said a little too much tonight. ”
"Don't say that!" The odds say, "We're all counting on you for guidance!" ”
"That's right!" Boss Zhang also chimed in, "Caishen, you have really become the God of Wealth for our big guys now!" If you're afraid of losing your life, you can talk less or don't talk at all, just vote with me. ”
In fact, Boss Zhang is most concerned about lottery players in his betting station to buy lottery tickets, now we know that every buy must win, there are not a few people who follow the order, and the stakes are much higher than usual when they choose themselves, so he is bent on keeping Wubi this important customer.
"That's right!" Xiao Odds said, "Of course you don't want to lose your life, but Boss Zhang, you have to worry more in the future, write down what Caishen buys every day, and don't give us a chance not to leak it when the time comes!" ”
"Don't worry! Blessed to share, my Lao Zhang is not the kind of person who eats alone. Boss Zhang said.
Seeing that the topic was shifted to Wu Bi for a while, and the two students in front of him didn't seem to know how to answer their own questions, Yang just shook his head, turned around to the counter and picked up a few thick lottery tickets that Boss Zhang had played for him, put them in his box and planned to leave, when he suddenly heard Lao Song shouting behind him: "Old Yang Tou, you haven't told the big guy the answer to your crooked heresy!" Why is it patriotic to buy the Chinese team to lose? ”
Yang just stopped, glanced at him, sighed slightly, and was about to move forward, only to hear someone at the door say loudly: "The reason why everyone buys lottery tickets to bet on the Chinese team to win is nothing more than to share the glory and disgrace with the motherland, and win and lose together, but everyone does not consider the relationship between football games and football lotteries." ”
"Shi Yuliang!" Chang Zhan and Wu Hope shouted in unison with a man who looked like a college student standing at the door.
"Hello Mr. Yang!" Shi Yuliang greeted Yang Fu respectfully, and waved his hand to Wu You.
Yang nodded at him and asked, "Do you also like to buy football lottery?" ”
"I've never bought it." Shi Yuliang replied.
"And what are you doing here?" Yang asked again.
Shi Yuliang turned his gaze to Chang Zhan and Wu You, and said, "I'm here to find the two of them to team up to play CS (Counter-Strike, Counter-Strike). ”
Yang didn't sink his face when he heard this, and said, "The final exam is coming up next month, but you are busy playing games in the middle of the night, are you so confident that you can pass my "Probability Theory and Mathematical Statistics"?" ”
Shi Yuliang said with a smile: "Everyone says that Mr. Yang's "Probability Theory and Mathematical Statistics" is difficult to learn, and it is even more difficult to pass the exam. If I don't accept their challenge, it's as if I'm afraid of them. ”
"That's it!" Chang Struggle said on the side, "With the few broken guns next door, I dare to challenge, I have to blow their heads well!" ”
Hearing that he was going to play CS, Wu You suddenly became excited and said, "Yes! Headshots, a must! Nothing has been going well lately, and it's just a matter of taking them to defeat. ”
Yang but glared at the two of them with a blue face, but heard Shi Yuliang say: "But tonight I came here really unintentionally to insert willows, and I happened to hear Mr. Yang you mentioned the problem of buying football lottery and patriotism, many people think that football lottery is just a game, but I think it is a very complex economic problem." ”
At this time, the little odds interjected: "This little brother, although you don't buy lottery tickets, but I think your point of view is very unique, then you might as well analyze it for us from the perspective of mathematics and economics." ”
Shi Yuliang continued: "Teacher Yang, just now I used the mathematical model theory you taught us to think about it briefly......
"What is the mathematical model?" Small odds interrupted him and asked.
"A mathematical-model is an abstract, simplified structure about parts of the real world and for a particular purpose." Shi Yuliang explained, "Specifically, it is an equation or inequality established by letters, numbers and other mathematical symbols, as well as mathematical structural expressions such as charts, images, and block diagrams that describe the characteristics of objective things and their internal relationships for a certain purpose. It is a science that combines mathematical theories with practical problems. It reduces real-world problems to corresponding mathematical problems, and on this basis, uses mathematical concepts, methods and theories for in-depth analysis and research, so as to characterize practical problems from a qualitative or quantitative point of view, and provide accurate data or reliable guidance for solving real-world problems. ”
"Sounds so profound!" Small odds sighed.
"Let's talk about something that we big guys can understand!" Lao Song said, "Save the old man and let him scream there." ”
Shi Yuliang smiled and said, "Then let's talk about the game that the Chinese team will play in Hong Kong tomorrow!" May I ask who bought the Chinese team to win? ”
Shi Yuliang looked at everyone, everyone looked at me, I looked at you, and suddenly Chang Struggle stabbed Lao Song with his hand and said, "You bought it." ”
"Me? Oh...... Oh......" Lao Song patted his head and said, "I bought 800 yuan just now, but I actually bought it for your teacher, Lao Yang." ”
"And how many people do you think think the same way you do?" Shi Yuliang asked.
"There must be a lot of patriotic people!" Lao Song glanced at everyone with disdain and said, "Although the world is declining, I believe that there must be more than 800 of me in the city!" The whole of China is thousands of me! ”
"Don't take it for granted there, many people support the Chinese team but don't buy lottery tickets, and there are also many people who buy lottery tickets but don't fancy the (Zhong) national team at all." Boss Zhang said, "In addition, there are many people who don't like to bet too early, they like to buy the game of the day, so most people who buy the game of the Chinese team should bet tomorrow!" ”
"Boss Zhang, right? How many football lottery betting shops are there in the city? Shi Yuliang asked.
"Well! I'll calculate, if you add sports lottery, the words of the five districts will ......," Boss Zhang said, snapping his fingers.
"Twenty-three." Small odds said casually.
Boss Zhang looked surprised and said, "Oops! I didn't see it, you're clear! You don't bet in every store, do you? ”
"It's just that you want to make a few more friends, if you want to bet, the biggest bets are placed on you, Boss Zhang." The small odds said, "Besides, now that you have invited the color god in the store, I will have to come to worship every day in the future, right?" ”
Shi Yuliang pulled back the topic and said: "Boss Zhang, how many lottery players often come to your store?" ”
"At least, there must be hundreds of people!"
"Let's say it's a hundred, and twenty-three betting shops are two thousand three hundred." Shi Yuliang calculated.
"There are also a lot of bettors who like to place bets online or on their phones." Small odds added.
Shi Yuliang continued to calculate and said, "If it triples again, it will be six thousand nine hundred." There are more than 20 large and small cities in the province, and if you roughly multiply it by ten times, it is 69,000, and there are 34 administrative regions in the country, which is ......"
"Two million three hundred and forty-six thousand." The result is obtained by the small odds arithmetic.
"The calculations are accurate." Yang nodded, then turned his head and glanced at the small odds.
The series of numbers in his ears made Lao Song a little impatient, and shouted: "I said small odds, when will you become big data!" ”
"Good! A conservative estimate is that there are at least two million football lottery players in China. Shi Yuliang said, "So as a lottery player, what is the relatively average betting amount?" ”
"At least two dollars a bet." Boss Zhang said.
Lao Song pursed his mouth and said, "I've seen a game bet hundreds of thousands." ”
The implication is that everyone else is someone who has never seen the world.
Hua Cub snorted lightly and whispered, "Hundreds of thousands of dollars are nothing big in Lixing's sky casino!" ”
Long Xirui tugged at her hand and motioned not to talk too much.
Lao Song probably didn't hear Hua Cub'er's ridicule, and said proudly: "If you want me to say, if the average single bet is less than 100 yuan, it is not a lottery player at all." ”
This sentence immediately aroused the dissatisfaction of many people, and Chang Struggle said loudly: "You can't say that!" A real technical lottery player should guess a jackpot of thousands of dollars with a small amount of money, and that is called ability! ”
"It's the first time I've heard that thousands of dollars are also called grand prizes!" Lao Song sneered and said, "I bought 14 games, basically each order is over 10,000, and if I win, it will be 5 million, so it is called a grand prize!" ”
"But have you ever been hit?" Wu You also joined the argument, saying, "If that money is given to us, it will definitely not be your kind of betting strategy......"
Lao Song has always looked down on those college students who have no fixed income and are quite poor in betting, and at this moment I saw that two students dared to speak disrespectfully to themselves, accusing themselves of lack of skill in betting, and couldn't help but be angry, and scolded: "Shut up for me, BB less in front of me, don't pretend to be a lottery player here if you don't have money, go back to school and gnaw your books!" ”
Seeing that the more the two sides talked, the more angry they became, Xiao Odds hurriedly stood up and persuaded: "Everyone said a few words, did you forget the class friendship that used to advise each other so quickly?" Huh! Shi Yuliang, where did you just go? Yes, the question of the amount of betting, some people are willing to bet a little pleasure, two pieces, several pieces, and those who like to throw, a random ball is hundreds of thousands or even millions, but there are also a lot of people. ”
Shi Yuliang took over the topic with interest and said: "Then you might as well compromise it, if you bet an average of 100 yuan per person, the amount of bets in the country will at least exceed 200 million." So, do you know what 200 million yuan can be used for? ”
