You can put this solution on YOUR website! A and B play a game in which their chances of winning are in the ratio 3:2. Find A's chance of winning of at least three games out of the five games played.
--------
Prob (win a game ) = 3/5
Prob (winning at least 3 games)
= 1 - P(winning 0,1,or 2 games)
= 1-binomcdf(5,(3/5),2)
= 0.68256
