WebMar 22, 2024 · One of the most common notations for the probability of A given B is P ( A B ). Another notation that is used is PB( A ) . Formula There is a formula for conditional probability that connects this to the probability of A and B : P ( A B ) = P ( A ∩ B ) / P ( B ) WebApr 17, 2024 · If the events A and B are independent, then P ( A ∩ B) = P ( A) P ( B) and not necessarily 0. You are confusing independent with mutually exclusive. For instance, you toss two coins. What is the probability that both show heads? It is 1 2 × 1 2 isn't it? Note that the coin tosses are independent of each other.
