COMPLETE ALL SECTIONS AD Assume that we have two events A an

Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know PA) - 0.25 and P(B) - 0.75. a. What is PA B) b. What is P(A 1 B) Is PA B) equal to P(A)? v Select c. Yes and B

Solution

1. a) Intersection is zero

b) Zero ( Probability of intersection of sets A, and, B)

c) Yes. These are independent events

2. Events A, and, B are independent

3. Mutually exclusive events are not independent

If A occurs, the dependent event B does not occur. These means these are not independent
