= An urn contains 4 coins labeled 1,2,3,4. The probability of heads for coin i is i/5, i = 1,2,3,4. A coin is randomly chosen and the same coin is) flipped 5 times. Let Y be the number of heads in the 5 flips and let X be the chosen coin.
(d) What is the MSE if you use 1 as your prediction of Y (and you don't know X)? (e) What is Cov(X,Y)? (f) What is the best prediction of Y to minimize MAD when X = 2?
