随机变量分为离散型随机变量与 非离散型随机变量两种，随机变量的函数仍为随机变量。有些随机变量,它全部可能取到的不相同的值是有限个或可列无限多个，也可以说概率1以一定的规律分布在各个可能值上。这种随机变量称为"离散型随机变量"。

本文论述了离散型随机变量的次序统计量的分布律及其有关推论。
In this paper, we study the distribution law of order statistic of discrete type random variable.

并且将它推广到任意具有可数无限分布列的离散型随机变量和随机向量。

介绍了用离散型随机变量的二项分布函数从试题库随机选题的数学模型。

That's different when you have continuous values-- you don't have P because it's always zero.
和离散型随机变量的分布不同的是,连续型随机变量的分布中,某一点的概率值始终是零
-
You have discrete random variables, like the one I just defined, or there are also--which take on only a finite number of values-- and we have continuous random variables that can take on any number of values along a continuum.
就像刚定义的,是一个离散型随机变量,随机变量还可以有无限种取值,也就是连续型随机变量,随机变量可以取某一区间的一切值
