Answer asap 1 more than 3 times a number is less than the sum of 3 and the same number a. 3x + 1 < x + 3 b. 3x + 1 = x + 3 c. 3x − 1 > x + 3 d. 3x − 1 = x + 3

Let x have probability generating function gx (s) and let un generating function u(s) of the sequence uo, u1, satisfies p(x > n). show that the (1- s)u(s) = 1 - gx(s), whenever the series defining these generating functions converge.
