Good Evening Sir, I have watched the full probability course of yours and it was very helpful. I have one doubt Sir .
Q. V Anand and Gary paly a series of 5 chess games. The probability that V Anand wins a game is 2/5 and the probability of Gary winning is 3/5.There is no probability of a draw. The series will be won by the person who wins 3 matches.Find the probability that Anand wins the series (The series end the moment when any of the two win three matches.)
Options:- a. 992/3125 b.273/625 c.1021/3125 d.1081/3125
Is there any short way of doing this question?
