独立性是概率论中一个重要的基本概念,它在概率计算的简化和证明中有着广泛的应用,同时也是解决一些实际问题的基础.本文就独立性概念和与之易混淆的概念之间的关系加以分析说明.1.两事件独立与两事件互斥之间的关系定义1:对两个事件A与B,如果P(AB=P(A)P(B),则称事件A与B独立.由定义易知,独立性是事件间的概率属性,而两事件互斥是指两事件不能同时发生,其实质是事件间
Independence is an important basic concept in probability theory, which has wide application in the simplification and proof of probability calculation and also serves as a basis for solving some practical problems.In this paper, the relationship between the concept of independence and the concept of confusion The relationship between two independent events and the mutual exclusion of two events Definition 1: For two events A and B, if P (AB = P (A) P (B), then the events A and B Independent. By definition, independence is the probability attribute between events, and the mutual exclusion of two events means that the two events can not occur at the same time. The essence is the inter-event
