Question

Suppose that Roberto, a well-known major league baseball player, finished last season with a .325 batting average. He wants to calculate the probability that he will get his first hit of this new season in his first at-bat. You define a success as getting a hit and define the random variable x=number of at-bats until Roberto gets his first hit.

19. What is the probability that Roberto will get a hit on his first at-bat?

20. What is the probability that it will take him at most 3 at bats to get his first hit?
