Webb1 juli 2024 · When calculating probability, there are two rules to consider when determining if two events are independent or dependent and if they are mutually exclusive or not. The … WebbThe above formula holds as long as P(A) > 0, since we cannot divide by 0. ... Now, for events A and B that may be dependent, to find the probability of A and B, we multiply the probability of A by the conditional probability of B, taking into account that A has occurred. Thus, our general multiplication rule is stated as follows:

WebbThe 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 … Probability with general multiplication rule "At least one" probability with coin … To get the probability of both events being true.
