Why does the banker only make money and not lose money? Because the dealer determines the winning amount according to the winning probability. Simply put, if the probability of winning is one in ten, that is to say, one out of ten lottery tickets is winning. Suppose that each lottery ticket sells 2 yuan money, and ten lottery tickets can sell 20 yuan. These ten lottery tickets were bought by ten people respectively. They won the lottery. He won the lottery. How much will he win? He can only win 20 yuan at most, and the dealer can only give him ten times the lottery price at most. If he wins again, the dealer will lose money. In other words, when gaming companies formulate winning rules, they must first use statistical principles to calculate the probability of people winning. If the probability is high, the banker will give you less money; if the probability is low, he will give you more money. The winning probability of ordinary people is 1%, and the bookmaker will give ordinary people a bonus of 100 times at most. Generally speaking, ordinary people feel great when they give 70 or 80 times, but they don't know that the other 20 times will be earned by the bookmakers themselves. But how many people will calculate the chances of winning the prize so carefully? In addition, it is even more dazzling to divide him into grand prize, first prize, second prize, third prize and encouragement prize. Who knows that? As a result, the dealer made more money. Besides, what if it is calculated? Everyone believes that he is lucky. As long as he wins the prize, even if the bonus of 100 is 80 times, the winner will earn! Both the winners and the dealer made money, and those who didn't win lost. Therefore, the so-called lottery is a social activity in which the gaming company shares the money of the majority of the winners with a few winners. This is statistics.
