perplexus.info :: Probability : Fair Pairs

Fair Pairs (Posted on 2007-03-05)

The probability of drawing a pair of cards from a standard deck of 52 and having those cards be different colors is 26/51, slightly over 50%.

What is the smallest number of cards that need to be removed from the deck so that the probability of drawing a mismatched pair is exactly 50%?
