摘要
市场上活跃的摸彩活动的基本原理,与概率论中摸球模型理论基本一致。它有公平性的一面,也有欺骗性的一面。而要确保公平性,就要尽量使摸彩者无法知道已摸过的人数。
The basic theory of getting prize is in agreement with the theory of getting sphere model in probability. It has the equity as well as the deception. In order to ensure the equity. it needs to make sure that the people who get prize don't know the exact number of people who have done it.
