摘要
“概率元”是处理随机变量分布的灵活方法,但在当下课堂教学中并没有得到足够重视.该方法可定义异质随机变量的联合分布,进而可以用于推广全概率公式、贝叶斯公式以及复杂的概率计算.
“Probability Unit Method”, as a smart probability technique, is seldom touched in the corresponding textbooks. As a useful definition of the distribution of a random multivariate with different types of components, it can be used in generalizing “Total Probability Formula” , “Bayes Formula” and some complex probability computation.
