Problem
Hugo plans to buy packs of baseball cards until he gets the card of his favorite player, but he only has enough money to buy at most packs. Suppose that each pack has probability of containing the card Hugo is hoping for.
Let the random variable be the number of packs of cards Hugo buys. Here is the probability distribution for :
What is the probability that Hugo buys at most packs of cards?
