For a game, a player takes a turn by spinning a spinner and rolling a number cube. The spinner has three equally sized sections colored red, yellow, and blue. The number cube has has sides numbered 1 through 6. The table shows all possible outcomes of a turn. Red, 1 Red, 2 Red, 3 Red, 4 Red, 5 Red, 6 Yellow, 1 Yellow, 2 Yellow, 3 Yellow, 4 Yellow, 5 Yellow, 6 Blue, 1 Blue, 2 Blue, 3 Blue, 4 Blue, 5 Blue, 6

The discrete random variables x and y take integer values with joint probability distribution given by f (x,y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x,y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
