WebSep 21, 2016 · 1. What is the probability of A given A union B? We know that p (A) = 0.5 p (B) = 0.3 p (AB) = 0.1. From my understanding of conditional probability i think it should be p (A)/p (A union B) . Is this correct? Could I solve this problem using the definition of conditional probability p (A B) = p (AB)/p (B) and then applying the distributive law.
