Probability of a and b happening

WebbProbability Theory Multiplication Rule: The probability of both A and B occurring is equal to the probability of B times the probability that A occurs given that B has: P (AB) = P (B) P (A B). Consequently, the conditional probability is given by P (A B) = P (AB)/P (B). WebbThe probability of P (A or B) happening at the same time is simply P (A) + P (B) — P (A and B) We minus P (A and B) so that we take away their overlap once to avoid double counting. (~)...
