MAT 133 4-3 Homework Help | Questions with Solutions. So you need to multiply your individual probabilities together to see if it equals the probability of them both happening. Which pairs of events are independent? P(J) = .50, P(K) = .40, P(J ∩ K) = .3. P(J) ×P(K) = .5 ×.4 =.2 and P(J ∩ K) = .3, therefore J and K are not independent. P(J) = .60, P(K) = .20, P(J ∩ K) = .12. P(J) × P(K) = .6 ×.2 =.12 and P(J ∩ K) = .12, therefore J and K are independent. P(J) = .15, P(K) = .5,...
