摘要
服从几何分布的多个独立离散型随机变量其最小值和最大值是一个含有多参数的离散型随机变量,本文证明了其最小值随机变量仍服从几何分布,并给出了最大值随机变量的概率函数、数学期望和方差。
Abiding by geometric distribution,discrete independent random variable's minimum and maximum are poly parameters discrete variables. This passage testifies that its minimum random variables abide by geometric distribution and offers its maximum random variables probability distribution, mathematical expectation and variance.
