Question 367165
It is to A's advantage to play as short a series as possible because the probability of winning each game is below 50%
in a 3 game series.
.4^2=.16 win....1st 2 games....lose .6^2=.36
.
1-(.16+.36)=.48
.
.4*.48=.192....win 2 out of 3.....lose .6*.48=.288
.
.16+.192=.352 chance of winning a 3 game series
As you can see the chance of winning a 3 game series is less than the chance of the team winning a single game and it gets worse the longer the series played.
