2.1 Suppose the random variables X and Y are independent, and have the joint probability density

Name: 2.1 Suppose the random variables X and Y are independent, and have the joint probability density function: f(x, y) = 1/(x^2 y^2) x > 1; y > 1, 0 otherwise. Let U = X/(X + Y) and V = X + Y. Show that the joint density function U and V is given by: f(u, v) = 1/(u^2 (1 - u)v^3) 1/u < v; 0 < u < 1/2 and 1/(1 - u) < v; 1/2 <= u <= 1, 0 otherwise
