Answer:Step-by-step explanation:Assuming it is equally likely to pick any number from 0 to 9, or in other words every number has 1/10chance to be picked, that mirrors the chance of getting a home run for the baseball player.So, one time at bat would be one time picking a number. Since there are two times at bat per game, that would be represented by two picks.We want to have one number represent a home run, while every other number will mean not a home run. So,we want to know how many picks it would take to get this home run number five times. once we have that we divide the number of picks by 2 and round up to get an estimation for number of games.Again, this only works if each number is equally likely to be picked. Or if there is a number on there that has a 10% chance to be picked. Then it has to be that number to represent the home run.
