Many say that baseball, which is commonly called America's National pastime, is a game with a low success rate. Consider
Mookie Betts, one of the greatest players the sport has ever seen. He had a batting average (BA) of .346 during the 2018 season.
His batting average was the highest of all players for that year.
A player's batting average is computed by dividing the number of times a player has a hit by the player's total number of at-bats.
BA=
Number of Hits
Number of At-Bats
Notice that this formula looks a lot like a probability where the sample space is the set of all at-bats and the event is getting a hit.
When fans talk about batting averages, they commonly think of it in terms of probability. That is, if a player is batting .250, then
there is a 25% chance that they will get a hit at their next at-bat.
1. Do you agree with the interpretation of the batting average as a probability? Is it possible to compute the theoretical
probability that a player will get a hit when at bat?…
