How many pairs are there in a standard 52 card deck?

Solution

Out of a deck of 52 cards, we have 52 choices (or 52 possible cards that could be drawn) for the first card.

Because we don\'t put the first card that we pick back into the deck before picking the second card, we only have 52 - 1 = 51 choices for the second card

so total numbers of pairs = 52 * 51 = 2652
