You randomly picked 4 chocolates in a box containing 3 Kitkat, 2 Snickers, and 3 Hershey's. If X is the number of Kitkat and Y is the number of Snickers in the sample, find a. the joint probability distribution table of X and Y; b. P[(X, Y ) A], where A is the region that is given by {(x, y) | x + y 2}. c. f(y|x=2) for all values of y (tabulate); d. P(X = 0 | Y = 2).
