Consider 4 sequential flips of a fair coin.

a. Let A be the event that 2 consecutive flips both yield heads and let B be the event that the first OR last flip yields tails. Prove or disprove that events A and B are independent.

b. Let X be the random variable of how many pairs of consecutive flips (of the 4 total flips) both yield heads. What is the expected value of X?
