Question & Answer: Joint distributions and independent variables 2.54. The joint probability function of two discrete random variables…..

Please help with these two questions…

Joint distributions and independent variables 2.54. The joint probability function of two discrete random variables X and Y is given by fíx.y)cx or 1,2,3 and y = 1, 2, 3, and equals zero otherwise. Find (a) the constant c, (b) P(X = 2, Y = 3), (c)Pils X s 2.Ys 2), (d) P(X 2), (e) P(Y < 2), (f) P(X = 1), (g) P(Y = 3). 2.55. Find the marginal probability functions of (a) X and (b) Y for the random variables of Problem 2.54 (c) Determine whether X and Y are independent.
