RE: Geometric Problem??

Elissa, I see you have found an answer to your problem so I will only add and afterword.. Some years ago (95? maybe) I investigated the expected length in comparison to the actual length of world series contests. I submitted to the Reader REflections of the Mathematics Teacher, a spreadsheet solution to this question which included the additional option of a "home field advantage". You might want to use this as a followup questions to students who found the original question interesting... Given that the two teams are even, but the home team has a prob of p of winning, what is the expected length of a world series. To simplify the problem give a specific prob, say .55 or .6 for the home team...

Hi everyone.
I assigned this problem to my class and I'm not sure how to get the answer, except by listing all the possibilities (and even then I'm not sure). Any helpful hints or actual solutions are greatly appreciated. I'm not sure where I got this  maybe at NCSSM  but I decided to embellish it and got myself into a world of trouble.
Two teams, A and B, are playing a series until one team gets four wins. In Scenario 1, team A and team B are evenly matched, and in Scenario two, Team A has a 70% chance of winning each game. What is the expected length of each series, theoretically? (they simulate it first) What is the theoretical probability each team wins the series? (Is it the same as the probability of winning each game?)
