The world series is a contest to determine the first of two teams to win four games. Assume that each team has an equal chance of winning any particular game and winning is independent of what happens in any other game. Find the average number of games. Give your answer as a fraction reduced to lowest terms.

Yes but is there any way you or someone else could explain to me what that means? We haven't done this in my Statistics class yet.
