摘要
由随机事件概率的加法定理得到任意有限个随机事件积事件概率计算的一个公式,运用该公式推导出n维随机向量的最小次序统计量的数学期望公式,并给出了相应的证明。
Based on the addition theorem of random events probability,a formula about the probability calculation of the plot events of any finite random events is obtained.The formula is used to elicit the mathematical expectation of the smallest order statistics of the n-dimensional random variable,and the proof of the mathematical expectation is also presented.
