Question 1 1 pts Suppose that the joint PDF of X and Y is fxy (w, 2) = w + 2 for we [0, 1] and z ( [0, 1] (and zero otherwise). Note that the marginal PDF of Y is fy (@) = \\ + 2 for = = [0, 1] (and zero otherwise). What is E( X Y = 0.5), the conditional expectation of X given that Y 0.5? 1 1.57 O 0.57 0 0.59
