Each of 5 gift bags contains x toys. Tyler adds 6 more toys to each bag. Altogether, the first bags contain 49 toys. Complete all three parts: draw a tape diagram, write an equation, and solve for x. What is 5(x+6)=?​

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.
