The Attempt at a Solution
My attempt at the first two parts is uploaded I am really confused on how to do game 6 and 7. Also I am a bit confused on how what I did worked in P(y=5), as the professor worked those parts out in class and I have forgotten since last class. Why is it 2 choose 1 is it because either team A or team B can win one game? Also why is it 4 choose 3, I am really lost on this part. So if I am assuming that they have played one game because the winning team has to win 4 total games, and the losing team has to win either game 1,2,3 or 4 and cannot win the last because the series would be over. Thus since they lost 1 they would have to play 4 more which is where the 4 on the top comes from, but why the three that would only be three wins thus they wouldn't win? Am I correct
