1) a) Let X1, X2 denote two independent random variables, each with a χ2 (3) distribution. Find the joint p.d.f. of Y1=X1 and Y2=X2+X1. Here note that the support of Y1, Y2 is 0 1 < y2 < ∞. Also find the marginal p.d.f. of each of Y1 and Y2. Are Y1 and Y2 independent?
b) Find the joint pdf of Y1 = X1 + X2, Y2 = X1 + X2.
c) Find the marginal pdf of Y1.
