Consider a pair of random variables X and Y, each of which take on values on the set A (1.2,3,4,5). The joint distribution of X and Y is a constant: Pxyx,y)-1/25 for all(x.y) pairs coming from the set A above. Let the random variable Z be given as the minimum of X and Y. Find the probability that Z is equal to 5.
