Baseball A baseball player’s batting average changes every time he goes to bat and therefore should not be used as the probability of his getting a hit. However, we can still make a subjective assessment of his ability. a. If a player with .3 probability of getting a hit bats four times in a game and each at-bat is an independent event, what is the probability of the player getting at least one hit in the game? b. What is the probability of the player in part (a) starting off the season with at least one hit in each of the first 10 games? c. If there are 20 players with .3 probability of getting a hit, what is the probability that at least one of them will start the season with a 10-game hitting streak?

Solution Summary: The author calculates the probability of a baseball player getting at least one hit in four batting turns based on the rule of independence of events.
