Please assist with the following Statistics question: Consider rolling a fair 6-faced die twice. Let A be the event that the sum of the two rolls is exactly 6, and B be the event that the first one is an even number.
(a) What is the probability that the sum of the two rolls is exactly 6 given that the first one is an even number?
(b) Are event A and event B independent? Explain.
