7. If the r.v.'s X and Y have bivariate normal distribution with parameters ₁ = 3.2, 2 = 1.44, 0₁ = 12,02 = 16 and p = 0.7, determine the following quantities: (a) E(X), E(Y), Var(X), Var(Y), p(X, Y), and Cov(X,Y). (b) the distribution of X and the distribution of Y. (c) the probabilities P(0.8 < X < 4.2), P(Y > 14).
