Hi there,

I am so lost on this question. I know I need to use CDF approach, but I couldn't figure it out.

3. Let the joint probability density fiJnction for (X, Y) be xf(x,y) : :y, x>0, y>0, 3x+y<3, zero otherwise. k) Find the probability distribution of W : X + Y. 1) Set up the integral(s) for the C.d.f. of V = X x Y, FV( V).You do NOT have to evaluate the tntegral(sj). In) Set up the integral(s) for the C.d.f. of U : Y/X, FU( u ).You do NOT have to evaluate the integral(s).
