WebThe general multiplication rule For any two events, we can say that P (\text {A and B})=P (\text {A}) \cdot P (\text {B} \text {A}) P (A and B) = P (A) ⋅ P (B∣A) The vertical bar in P (\text {B} \text {A}) P (B∣A) means "given," so this could also be read as "the probability that B occurs given that A has occurred." WebThe multiplication principle is a useful tool when counting the number of ways something can be done. The principle describes the number of ways to order things when there are several events put together. The principle applies to Factorials. Ordered sets with …
