WebP (A B) is conditional probability. P (A B) means the probability that A happens given that B happens, in other words, P (A B) is the probability of A occurring based on the knowledge that B occurs. If the events A and B are independent, P (A B)=P (A), the outcome of B does not influence the outcome of A, so the probability of A occurring doesn ...
