关于全概率公式的一点注记

A REMARK ABOUT THE TOTAL PROBABILITY FORMULA

通过"有限总体、等可能概率"条件下,某些应用全概率公式求解问题的研究,我们得到了一个简单算法,并因此提出了一个关于全概率公式的一个注记的命题,同时给出了全概率公式注记命题的证明及实际应用的例子.

Under the condition of finite population and equal probability, the total probability formula in some applications is discussed, from a simple algorithm is obtained. A proposition about the whole probability formula is put forward. The proof of the proposition and practical application example of the total probability formula are presented at the same time.
