If X and Y are independent and identically distributed uniform random variables on (0, 1), compute the joint density of U = X + Y, V = X/Y The joint probability density function of X and Y is given by f (x, y) = 6/7(x2 + xy/2) 0 < x < 1, 0 < y < 2 (a) Compute the density function of X. (b) Find P{X > Y}. (c) Find P{Y > 1/2|X < 1/2}. If X and Y are independent binomial random variables with identical parameters n and p, show analytically that the conditional distribution of X given that X + Y = m is the hypergeometric distribution.
