关于条件概率教学的注记

A Note of Conditional Probability in the Teaching

本文对条件概率进行补充说明.将条件概率看作事件域上的二元函数,并研究了其性质.指出了条件概率是事件域上的一种包含度.借助于条件概率的包含度解释,我们给出全概率公式的另一种理解.

In this paper, additional remarks about conditional probability are given. Conditional probability can be regarded as a binary function on the event-domain, whose properties are studied. It is pointed out that con- ditional probability is a type of inclusion degree on the event-domain. Another interpretation of the total probability formula is given by means of the inclusion degree interpretation of conditional probability.
