3If the deck is well-shuffled, any card can be in any position with equal probability. Therefore any card can be in the $25+14$th position with equal probability... Is there something I'm missing? – 2012-06-21

0I do not know the answer but I want to know that removal of 25 cards will have what effect on probability. – 2012-06-21

1The removal of the top 25 cards has no effect on the probability distribution of the bottom 27 cards. Each card remains uniformly likely to be any card in the deck. – 2012-06-21

0@ArpitBajpai: All permutations of the cards are equally likely. So the preliminary counting is irrelevant. You will be happy if you get an Ace or a Spade. How many cards make you happy? – 2012-06-21

0There will be 16 cards or in other words favourable events. – 2012-06-21
