| 摘 要： | 生活中,摸彩的人们总以为越先摸,中彩的可能性越大,其实不然！为此本文从概率角度建立了数学模型,证明了每个摸彩者中彩的机会均等,与先后摸彩顺序无关。同时,通过分析在中彩时,已摸过的彩票数目的数学期望,向彩票发行者提出了几点建议。

| Abstract: | In daily day, people drawing the lottery tickets at random,assume that the earlier they draw,the more likely they are to win the prize. Acctually,that is not the case! The Chances to win the prize are demonstrated,by making mathematical model at the angle of probability,eaqual to everyone,but nothing to do with the order to draw in. At the same time,according to analysis the mathematical expectation of the number of drawed tickets,this essay is trying to raise some advice for the department responsible for the work to conside. |
