摘要
通过求分布函数和利用分布函数求随机变量的概率两个方面讨论分布函数的两种定义的异同,并对离散型和连续型随机变量都给出了结论.最后简单介绍连续型随机变量的几个特殊性质.
Similarities and differences of two definitions of distribution function will be discussed from two aspects by seeking distribution function and solving the variable's probability.The conclusions of discrete and continuous variables will be respectively got.Special properties of a continuous random variable will be given at last.
