Now there are more than 500 people in your company, and less than 600 is unfair.
Suppose the total number of people is 550, and some people are 167.
When a place draws seven or ten places and draws six, it stands to reason that he has a chance of winning 1/5, and he will draw one of 0 12345.
But now, because of the total number of people, 100 people draw 5: 567, so we must give up, which is obviously unfair to him.
For 127, there is obviously no such influence.
Therefore, this lottery, regardless of the hundred digits, if the two digits of the ten digits are less than the last two digits of the total number of people in the company, the winning probability is higher.
The company had better draw lots by computer, which is very convenient to realize.
If you must draw table tennis, because there are not enough people, in order to ensure absolute fairness, you can only prepare as many table tennis as there are people, and each person corresponds to a ball.
Approximate absolute fairness, according to the formula:
Lottery number × company number ÷ 600+ 1 The lottery number of the calculator starts from 1.
Suppose there are 550 people in the company, and the three digits drawn are 123.
123× 550/600+1=113.75 ≈114 won the prize.
