Webb30 okt. 2012 · You have counted the probability that both happen twice. You have two events A is the event that a head comes up, and B is the event that a 5 or 6 comes up. The events are independent presumably, so the inclusion-exclusion formula gives: p ( A ∪ B) = p A + p B − p ( A ∩ B). Webb5 jan. 2024 · Given two events, A and B, to “find the probability of A and B” means to find the probability that event A and event B both occur. We typically write this probability in one of two ways: P(A and B) – Written form; P(A∩B) – Notation form; The way we calculate this probability depends on whether or not events A and B are independent or ...
