Problem 1 Let X, Y and Z be three jointly continuous random variables with joint PDF x + y 0 < x, y, z < 1 fxxz (x, Y, z) = otherwise 1. Find the joint PDF of X and Y. 2. Find the marginal PDF of X. 3. Find the conditional PDF of fxy|z (x, y|z) using fxyz (x, Y, z) fz(2) fxy|z (x, y|2) = 4. Are X and Y independent of Z?
