Question

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?

Answer 1

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 <b>cannot</b> both happen. P(A&B)=0.

On the other hand, P(A or B) = P(A)+P(B) = 0.60, or (B)

Answer 2

Ok thank you
