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. Who made a statistical argument?
