The sample space S of a random experiment is given by S = {a, b, c, d, e, f, g} and let A denote the event and A = {a, b, c, d} and B the event and B\A = {f, g} and B'nA = {a, b}. Pr (A') = 0.6, Pr(B) = 0.6, Pr(e) = 0.2 are known. Determine the following probabilities: (a) Pr(A U B); (b) Pr(A'|B). {"\"set difference operator and "| " conditional probability}
