摘要
一维随机变量函数的分布是概率论与数理统计教学的重点与难点,也是全国研究生入学考试的重点与难点.利用分布函数法构造一类适用于求解一维随机变量函数分布的直观解法,该方法基于数形结合思想构建统一方法求解一维随机变量函数的分布.确定了几类适用的场合,给出了3个典型例题的应用过程.
The distribution of one-dimensional random variable functions is a key and difficult problem in the probability theory and mathematical statistics,so is that in the national graduate entrance examination.Proposes a straight method of solving the distribution of one-dimensional random variable functions by constructing a distribution function. The proposed method can construct a unified method to solve the distribution of one-dimensional random variable functions by combined with a number shape union.Several applicable conditions are presented,and three typical examples are also given.
