摘要
探讨彩票方案的合理性 基本思想是 :从经济学的角度 ,考虑彩民购买一注彩票能获得的期望效用出发 ,用概率统计中的数学期望描述彩民买一注彩票能获得的期望效用 ,以方差来衡量彩民的风险度 ,根据“最大平均回报———最小风险”原理 。
The article is concerned with rationalization in lottery ticket schemes.Our fundamental view is:from the point of economics and expected utility the people who buy one lottery ticket can get,describe expected utility through probability statistics in mathematics,weigh the level of risk in variance and decide the most advantageous strategy according to the principle--the maximum average repayment to the minimum risk.
