CMI 2018 Objective
Suppose Kn be the number of strings having n X's and n Y's such that in all the prefixes of a string the number of X's is greater than the number of Y's. Now suppose you are standing at an edge of a swimming pool. You have a bag of n red and n blue balls.Now ... probability that you will not get wet. A) Kn / (2nCn) B) n Kn / (2nCn) C) Kn / (2n)! d) n kn / 22n
