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 … Webb24 apr. 2024 · If A and B are any two events, disjoint or not, then the probability that at least one of them will occur is P(AorB) = P(A) + P(B) − P(AandB) where P (A and B) is the probability that both events occur. TIP: "or" is inclusive When we write "or" in statistics, we mean "and/or" unless we explicitly state otherwise. strobe security solutions ltd
