摘要
主要讨论连续型随机变量分布函数与离散型随机变量分布函数在表达形式等方面的异同,总结连续型随机变量分布函数的主要表达形式,并讨论连续型随机变量分布函数的可导性。
The identity and difference in the expressional patterns between distribution functions of discrete random variables and distribution functions of continuous random variables are elaborated, and the main expressional patterns of distribution functions of continuous random variables are summarized, and the derivability of distribution functions of continuous random variables is discussed.
