Sania Mirza is to play with Sharapova in a three set match. For a particular set, the probability of Sania winning the set is √y and if she wins probability of her winning the next set becomes y else the probability that she wins the next one becomes y2. There is no possibility that a set is to be abandoned. R is the probability that Sania wins the first set. If R = 1/2 and Sania wins the second set, then the probability that she has won first set as well is nearly equal to a. 0. 74 b. 0. 46 c. 0. 26 d. 0. 54
