WebFor finding the probability of independent events we must go through with the formula of conditional probability which is given below: If the probability of events A and B is P(A) and P(B) respectively, then the conditional probability of event B such that event A has … WebThus, if two events A and B are independent and P ( B) ≠ 0, then P ( A B) = P ( A). To summarize, we can say "independence means we can multiply the probabilities of events to obtain the probability of their intersection", or equivalently, "independence means that conditional probability of one event given another is the same as the ...
