In their upcoming best of seven (the first team to win 4 games, wins the series) NHL playoff series, the Toronto Maple Leafs have been given 5 : 3 odds in favour of winning any particular game. What is the chance they will win the best of 7 series against the Montreal Canadiens? (Remember, it could take more than 4 games to win the series!)

P(W)=Probability that Toronto Maple Leafs wins each game

P(L)=Probability that Toronto Maple Leafs loses each game

P(W)/P(L)=5/3   ,  P(W)+P(L)=1    =>    P(W)/[1-P(W)]=5/3m    =>     P(W)=5/8  ,   P(L)=3/8 

We know that each team plays 6 times in the series.

A: Toronto Maple Leafs wins at least 4 games
