关于随机变量数字特征的一些问题探讨
iscussion of some problems on numerical characteristics of random variables
随机变量数字特征是概率论中重要的内容，在概率论与数理统计中有着广泛的应用。本文指出现行概论中数学期望等数字特征的性质在推理上的逻辑缺陷，澄清数学期望推理中的存在问题。
Numerical characteristics of random variables is important in probability theory, it has a wide range of applications in probability theory and mathematical statistics. In this paper, we point out that the existing introduction to mathematical expectation in numerical characteristics, such as the nature of logical flaws in the reasoning, clarify the mathematical expectation of reasoning problems.
