Mary drew 3 cards from a standard deck of cards (4
suits of 13 cards each) and drew the 4 of hearts,
the 4 of clubs and the 4 of diamonds. Abe claimed
the deck must be a trick deck as Mary should not
have been able to randomly draw three 4’s in a
row. Mary claimed there was actually a very slim
chance (.018%) that she could draw three 4’s in a
row, so it was possible for the deck to be fair.
