\fThe random variables X1 and X2 are independent and have the common distribution given in the table below: X = x 0 1 2 3 Px (ac) 0.2 0.4 0.3 0.1 The random variables W and Y are defined by W = max(X1, X2) and Y = min(X1, X2). (a) Calculate the table of probabilities which defines the joint distribution of W and Y
