Two events are mutually exclusive if their intersection is 1 if they have no sample points in common if their intersection is 0.5 None of these alternatives is correct. If P(A) = 0.5, P(B) = 0.4, and P(A ∩ B) = 0.25, then P(A ∪ B) = 0.9 0.65 0.15 0.35 If P(A) = 0.5, P(B|A) = 0.2, P(A ∪ B) = 0.7, then P(B) = 0.1 0.3 0.7 0.2
