摘要
随机变量的独立性在概率论中有着十分重要的意义.本文给出了离散型随机变量与离散型随机向量相互独立的概念,条件独立的概念,以及几种独立性的相互关系.
The random variables independence is very important in theory of probability.In this paper,we give the concept of mutual independence about the discrete random variables and the discrete random vector,the concept of conditional independence and mutual relationships of the independence.
