6. A value i is said to be the mode of a discrete random variable X if it maximizes p(x), the probability mass function of X. Find the modes of random variables X and Y with probability mass functions

p(x) = (-), x= 1,2,3,..., and 4! 34-y q(y) y = 0,

respectively.

p(x) = (-), x= 1,2,3,..., and 4! 34-y q(y) y = 0, 1, 2, 3, 4, y! (4-y)!
