Asked by .

The probability for event A is 0.4, the probability for event B is 0.2, and the probability of events A and B is 0.1.

Why are the events not independent?

The sum of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is greater than P(A and B).
The product of P(A) and P(B) is not equal to P(A and B).
The sum of P(A) and P(B) is not equal to P(A and B).

The product P(A)P(B) = 0.4 × 0.2 = 0.08, which is not equal to P(A and B) = 0.1. Independence requires P(A and B) = P(A)P(B), so the events are not independent. (Answer: The product ... is not equal to P(A and B).)
