Suppose X and Y are independent random variables. The possible values of X are -1, 0, and 1; the possible values of Y are 10, 20, and 30. You are given that P(X = -1 and Y = 10) = 0.05, P(X = 0 and Y = 30) = 0.20, P(Y = 10) = 0.20, and P(X = 0) = 0.50. Determine the joint probability distribution of X and Y.
