PLOT PDF NOT PMF

An information source produces binary pairs that we designate as Ox = {1, 2, 3, 4} with the following pmf: . 3 POINTS Px (k) = PXCD, VK E Qx . 3 POINTS px (k + 1) = Px(k) 2 2, k + 1 = 2, 3, 4. . 3 POINTS Px (k + 1) = Px (k) 2k , k + 1 = 2, 3, 4. - 3 POINTS Plot the PDF of these three random variables. - 4 POINTS Use the PDF to find the probability of the events: * {X
