Question

If P(A) = 0.60, P(B) = 0.30 and P(A and B) = 0.18, then events A and B  are?

1. independent and mutually exclusive events
2. independent but not mutually exclusive events
3. dependent but not mutually exclusive events
4. dependent and mutually exclusive events

Answer 1

They are independent since P(A)*P(B)=P(A and B)

They are not mutually exclusive events since P(A and B) != 0

The answer is 2
