Consider a box containing eight candies rapped in wrappers of different colors. Three candies are wrapped in blue color, two are wrapped in red, and three are wrapped in green. Two candies are selected at random from this box. If X is the number of candies wrapped in blue color are selected and Y is the number of candies wrapped in red color are selected, nd a) The joint probability function f (I, y) b) P[(X, Y) E A], where A is the region {(x,y)|x + y 5 1]
