A bivariate random variable (X,Y) has joint probability density function (pdf) f(3,9) = { 8xy, 0 < x < y < 1 0, otherwise. (a) Find the marginal distributions of X and Y. Use this to determine whether X and Y are independent. (b) Find the conditional pdf of Y given that X 5. What is the value of the probability P(Y > Ž|X = 3)? (c) Let the random variables U and V be defined by 5 X U = Y V=Y. (i) Find the joint pdf of (U, V) and clearly specify the domain of U and V. (ii) Find the marginal pdf of U.
