1. There are * * *10 million lottery tickets in this issue, including 2 million lottery tickets. According to the average probability, the winning rate is 20%, which means that there is one prize for every five.
Second, the lottery is random and unpredictable. That is, the buyer can't predict whether any lottery ticket will win or not. Lottery sellers can't guarantee how many consecutive lottery tickets are winning numbers.
Third, draw a conclusion:
1, if you buy lottery tickets less than or equal to 8 million, you may not win.
2. It is possible to win the lottery if you buy a lottery ticket that is greater than or equal to this period.
3. Winning the prize is a random result, which has nothing to do with the number of purchases within a certain range (the number is greater than or equal to one and less than or equal to eight million).
In the range mentioned above, the chances of winning the prize are equal.
Therefore, both statements in the question are incorrect.
The first-person statement is incorrect, because it does not necessarily mean certain. It is possible to buy one without winning, and it is also possible to buy fifty without winning, but the possibilities are not equal. Because the distance between these two values and the limit value of 8 million is not equal.
The second person's statement is incorrect, because winning the prize is a random result. You may win by buying one, and you may win by buying fifty. For the number of purchases within the range set by the mold, the chances of winning and not winning are equal. Of course, this probability equality is not a plane problem, but is increasing step by step.
For example, someone bought 8 million lottery tickets. If you win two million tickets at the beginning, the winning rate of the next six million tickets is zero. If you don't win at the beginning of 2 million, the probability will continue to be 50%, and so on.
