Events A and B are mutually exclusive. The probability of event A occurring is0.15; the probability of event B occurring is 0.45; what is the probability that A and B will occur? A.0.30 B.0.60 C.1 D.0.40 I think C am I correct?

surely not. A probability of 1 means it must occur. I think you have a typo anyway. If the events are mutually exclusive, then they cannot both happen. P(A&B)=0. On the other hand, P(A or B) = P(A)+P(B) = 0.60, or (B)

Ok thank you
