probability of ram picking up card no 23 = 1/23
similarly probability of ramesh picking up card no 22 = 1/23
and so on, after that if ramesh picks up card no 23 with prob 1/23 then his chance of winning after picking that card is 22/23 (because suresh can pick up any card with 22 cards smaller in number ) applying the same concept for all the cases we have req prob=1/23(22/23+21/23 +20/23 .............1/23)

11/23 (ANSWER) where 1/23 outside the bracket represent the probability of ram picking up any number and corresponding number in bracket represent his cahnce of winnning with that number
ANSWER 11/23
