Answer: 0.79, D
Work:
The value of the probability of (A or B) when A and B are mutually exclusive is equal to P(A) + P(B). There is no need to subtract the P(A and B) because the events are mutually exclusive which means that they never overlap and P(A and B) is therefore equal to 0. The answer is then 0.65 + 0.14 which equals 0.79, which is the answer.
