摘要
利用概率论对排列5、七星彩、22选5和超级大乐透四种彩票的中奖概率进行统计学分析,结果表明各类型彩票的收益(Y)均为负值,一等奖中奖概率均小于0.00001,各种彩票的标准离差率(即投注风险)分别为316.2262、1091.5748、84.5777和540.2034,说明彩民不能指望彩票成为生活的经济来源,更不能把中大奖作为致富的渠道。
The probability of sports lottery,including the arrangement of 5 numbers from 10,the arrangement of 7 numbers from 10,the Select 5 numbers from 22 and the Super Lotto,are analyzed in this paper.The results showed that the proceeds of all lotteries mentioned above,are negative,the probability of the highest prizes of all lotteries is no more than 0.00001,and the standard deviation rate is 316.2262,1091.5748,84.5777 and 540.2034,respectively.Therefore,people not only cannot live on getting the prizes of lottery but also cannot make a fortune by buying lotteries.
