That says that if you have independent probabilities, then the probability of two events is equal to the product of their probabilities.
意思是,几个相互独立的事件,其中两个事件同时发生的概率,等于他们分别发生的概率的乘积
This will generalize to probability of A and B and C equals the probability of A times the probability of B times the probability of C and so on.
简单的说,A和B和C同时发生的概率,等于A发生的概率乘以B发生的概率,乘以C发生的概率,以此类推
