What is the probability of a world series ending after 4 games? After 5 games? 6 games? 7 games?

Assume that each team has equal probability of winning each game, regardless of who has won the previous games.

(For the baseball-challenged, the World Series ends after one team has won 4 games. Ties are not possible.)

For some reason, I was thinking (correctly) "5/16" for the third and fourth terms in my "check," but I typed "5/8"
