The two events A and B have probabilities 0.2 and 0.4. Also P(A intersect B) = 0.08.
(a) Are the two events A and B independent? Explain.
well since 0.2*0.4=0.8 they are independent
(b) Find the probability that either A or B or both occur.
0.2+0.4+0.08=0.68
(c) Find the probability that neither A nor B occurs.
1-.68=0.32
(d) Find the probability that exactly one of A or B occurs.
0.2+0.4-.08=0.52
not sure could someone give feedbacks cheers
