Probability a or b
Webb18 juli 2024 · If A and B are any events then P(AorB) = P(A) + P(B)– P(AandB). If A and B are mutually exclusive events then P(AandB) = 0, so then P(AorB) = P(A) + P(B). Example … WebbP (A/B) is known as conditional probability and it means the probability of event A that depends on another event B. It is also known as "the probability of A given B". P (A/B) …
