Let random variable (RV) X with alphabet X = {1, 2, ..., 6} denote the outcome of the toss of a biased die such that its probability mass function (pmf) Px satisfies Px(1) = Px(3) = Px (5)= 3Px (2) = 3Px (4) = 3Px (6). (a) Determine the entropy of X, H(X), in bits. (b) Now the biased die is tossed once. If its outcome X is odd, a fair coin is tossed once; if X is even, the coin is tossed twice. Letting Y denote the number of tails obtained, determine I(X;Y) in bits.
