10 lucky spectators will participate in a lucky draw. The lucky draw consisted of 10 ping-pong balls of the same size in a box, and each ball had a number of prizes written on it.
If 10 lucky spectators participate in a lucky draw, each ball has a prize number written on it, then the fairness of the lucky draw can be guaranteed in the following ways: 1. Randomly divide the 10 ping-pong balls into two groups of five balls each. Then, the two groups of ping-pong balls were placed in two boxes. The five balls in one group were used as prizes, and the five balls in the other group were used as consolation prizes. 2 Let the participants choose the prize they want to win during the draw. If the participant made the wrong choice, the consolation prize would be awarded. If the participant chooses the right prize, the prize will be distributed according to the number of prizes written on each ball. In this way, all the prizes could be distributed fairly and no one would miss the prize because they chose the wrong ball. This way, the lottery would maintain fairness and everyone would have a chance to win a prize.
A unit held a lucky draw, and every employee had one chance to draw. There were six identical ping pong balls in the lottery box, three of which were marked with the number 1, two, and three.
The three balls with the number 1 on them were marked as the first prize, the two balls with the number 2 on them were marked as the second prize, the two balls with the number 3 on them were marked as the third prize, and the three balls without the number 1 on them were marked as the fourth prize, the fifth prize or the sixth prize. Each employee has a 1/6 chance of winning the first prize, 2/6 chance of winning the second prize, 3/6 chance of winning the third prize, and 1-1/6 chance of winning the fourth, fifth or sixth prize. Therefore, the probability of each ping pong ball appearing in the lottery box was: First prize:3/6 × 1/3 = 1/6 Second prize:2/6 × 2/3 = 4/18 Third prize:3/6 × 1/3 = 1/6 Fourth prize:1/6 × 1/3 = 1/18 Fifth prize:2/6 × 1/3 = 4/18 Sixth prize:1/6 × 1/3 = 1/18 Because every employee had one chance to draw the prize, they could not win the prize twice. Therefore, the first prize has a probability of 1/6, the second prize has a probability of 4/18, the third prize has a probability of 1/6, the fourth prize has a probability of 1/18, the fifth prize has a probability of 1/18, and the sixth prize has a probability of 1/18.
