Determine if events a and b are independent

WebEvents A and B are called mutually exclusive if they cannot both occur, that is, P(A and B) = 0. In this situation, P(A or B) = P(A) + P(B). Events A and B are called independent if the occurrence of one event has no effect on the probability of the other event occurring. In this situation, P(A and B) = P(A)*P(B).
