16. What is the probability that events A and B both occur?
(1) The probability that event A occurs is 0.8.
(2) The probability that event B occurs is 0.6.

Why is E?
I though the rule is to multiply both probabilities when you want both events to occur

The answer is P(A) * P(B) only when A and B are independent events.

From the question, we cannot assume that A and B are independent.
Hence E.

Sorry to re-open the thread..


It sounds to me P(A and P(B are both independent...but what kind of phrase or word will be needed to make P(A and P(B independent?

Thank you!
