随机变量的分布函数求解方法的讨论

Discussion of the Method for Distribution Function of Random Variable

结合实例归纳了求离散型、连续型、特殊型三种随机变量的分布函数求法,使问题易于理解,计算更为简便。并对这三种随机变量的分布函数进行了对比,讨论了其本质、表达形式等方面的异同。

This paper summarizes the method for discrete,continuous,special type of distribution function of random variable so that the problem of calculation is more simple and easy to understand. And the three kinds of the distribution function of random variable is compared, as well as the similarities and differences of their essence and forms of expression.
