From a sack of fruit containing 3 oranges, 2 apples, and 3 bananas, a random sample of 4 pieces of fruit is selected. If X is the number of oranges and Y is the number of apples in the sample, find
(a)the joint probability distribution of X and Y;
(b)P[(X,Y) € A), where A is the region that is given by ((a.v) |a+y <2).
