Problem 7.
What is the probability of the world series going to seven games, assuming that the two teams are evenly matched?
(The first team that wins four games wins the series.)

Let the teams be A and B.

The probability of the world series going to seven games equals
the probability that team A and team B each win exactly three games
after six games.

Therefore, the probability that team A and team B each win exactly three games after six games equals
