The joint probability function of two discrete random variables X and Y is given by f(x; y) =c(2x + y), where x and y can assume all integers such that 0 ≤ x ≤ 2; 0≤ y ≤ 3, and f(x; y) = 0 otherwise.
(a) Find the value of the constant c. Give your answer to three decimal places.
(b) Find P(X=0,Y=3). Give your answer to three decimal places.
