Two corporate baseball teams are scheduled to play a game together. They agree that if both teams attend or if neither team attends they will split the field costs. If one team is ready to play and the other does not appear, the costs will be borne by the missing team. A team does not attend if they have more than two injured players from a team of eleven. An individual's chance of injury is 5% and is independent of the other players. What is the probability that the cost will be paid by only one team?

2.99% probability that the cost will be paid by only one team

Step-by-step explanation:

The binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

Probability that a team plays:

A team plays if it has at most 2 injured players out of 11.

11 players, so

Each player with a 5% probability of injury, so

Then

In which

Each team has a 0.9848 probability of showing up to play.

What is the probability that the cost will be paid by only one team?

This happens if one team shows up and the other do not.

2 teams, so

Each team has a 0.9848 probability of showing up to play, so .

This probability is P(X = 1).

2.99% probability that the cost will be paid by only one team
