For two events, A and B, P(A), P(B), and P(A ) B). Are A and B independent events? (# means # P(A)= 0.4 P(B) = 0.5 P(A and B) = 0.2 Yes, the events are independent because P(B|A) = P(A) No, the events are dependent because P(A|B) = P(A) Yes, the events are independent because P(A|B)# P(A) Yes, the events are independent because P(A|B) = P(A) No, the events are dependent because P(B|A) # P(A) No, the events are dependent because P(A|B) # P(A)
