Determine the value c so that each of the following functions can serve as a probability distribution of the discrete random variable X:

(a) f(x) = c (x2 + 4), for a: = 0, 1, 2, 3;

(b) f(x) = c(2x)(33–x), for x = 0, 1, 2.

(a) f(x) = c (x2 + 4), for a: = 0, 1, 2, 3;

(b) f(x) = c(2x)(33–x), for x = 0, 1, 2.
