The joint distribution of X and Y is given in the following table: X = 0: 0.11 0.03 0.15 0.04 X = 1: 0.03 0.09 0.15 0.16 X = 3: 0.00 0.16 0.06 0.02 Y = -1 Y = 2.5 Y = 3 Y = 4.7 Find E(Y|X = 1). Give answer up to three decimal places.

The joint probability function of random variables X and Y is given by: y/x | 2 | 4 | 1 | 0.10 | 0.10 | 3 | 0.20 | 0.30 | 5 | 0.10 | 0.20 | (a) Give the marginal density of both X and Y as well as the probability distribution of X given Y = 3. (b) Give E(X) and Var(X). (c) Give E(X|Y=3) and Var(X|Y=3). (d) Give the covariance of X and Y.
