Problem 2 [All the \'new\" concepts covered since Midterm 1-1] The joint p.d.f. for two random variables, X and Y, is defined as axôy when this derivative exists. Suppose that random variables X and Y have a joint p.d.f. fry(z, y) = 8 (6-z-v)[a(z) _ u(z-2)][u(y-2)-u(y-4)] XY other x, y (a) Determine the marginal p.d.f. \'s fx(x) and () for X and Y
