If the team is equally likely to win as to lose
each game, what is the probability that they win

Best ResponseYou've already chosen the best response.0jesus another one. this one easier. only way to get at least 5 game in a row is 1) win all 7 2) win 6 lose 1 3) lose 1 win 6 4)win 1, lose 1, win 1 3) win 5 lose 2 4) lose 2, win 5

Best ResponseYou've already chosen the best response.0i think this is the only way. and since the probability of winning each game is 1/2, each of these events have probability \[\frac{1}{2^7}\] so if i am not mistaken the answer is \[\frac{6}{2^7}\]

Best ResponseYou've already chosen the best response.03 (1/2 )^7 + 2 (1/2) ^7 + 1 (1/2) ^7 = 6 (1/2) ^7 = 6/128 = 3/64 = .047 approx
