Question

Consider the following joint probability distribution on the random variables X and Y given in matrix form by Pxy P11 P12 P13 PXY-IP21 p22 p23 P31 P32 P33 P41 P42 P43 HereP(i, j) P(X = z n Y-J)-Pu represents the probability that X-1 and Y = j So for example, in the previous problem, X and Y represented the random variables for the color ([Black, Red]) and utensil type (Pencil,Pe pblackpen P(X = Black Y = Pen) = P(Black n Per) = .30 As such Evaluate the following quantities: 2, P(Y = 3) 3. P(x-3) 4. Calculate Px(x 1). Px(2), Px( 3) and Px 4) to generate the marginal distribution Px() Write the marginal distribution in the following form: a 1 5. Calculate the marginal distribution Py (y) again using the form: 6. Calculate marginal probability of Y conditioned on X 2. Py(X-2). Again write in the standard form 7. Calculate marginal probability of Y conditioned on X + Y-3, Pr(vXY 2). Again write in the standard form
