Apple stall draw lots
Suppose 100 apples have different qualities.
The probability of getting the best apple for the first time is1100, and the probability of not getting it is 99/ 100.
The probability of getting the best apple for the second time is 99/100 *1/99 =1100, and the probability of not getting it is 99/100 * 98/99 = 98//kloc-.
The probability of getting the best apple for the third time is 98/100 *1/98 =1100, and the probability of not getting it is 98/100 * 97/98 = 97//kloc-.
The probability of getting the best apple for the nth time is (101-n)/100 *1(101-n) =1/kloc.
The probability of getting the best apple is the same every time.
In fact, this question is equivalent to drawing lots. No matter what the lottery order is, it will not affect the fairness of the lottery results.
