| Abstract: | In this article,the total probability formula with the enforcement sure event conditional factors was given and proved,which is worth expanding for total probability formula of probability theory.Furthermore,base on the total probability formula with the enforcement sure event conditional factors,a simple but efficient method is proposed to calculate probability of random problem about enforcement sure event.Finally,the case shows clearly that this method applies widely. |
