I am in the beginning of learning statistics and I am trying to solve problems from the internet.
I found a problem with chess but I don't know how to solve it.
Could you help me ??
The problem is :
Two equals (equal possibilities for win) players are playing chess.
a. Is more possible to win someone 4 from 6 games or 5 from 9 ?
b. Is more possible to win at least 3 from 4 or at least 5 from 8?
c. How many games have to play a player so as the probability to win one of them to be > 0.9.
Thanks a lot for your help
