find the probability of selecting two red cards when two cards are drawn without replacement from a standard deck of cards

Answer 1

52 cards in a deck, 26 red cards.

26/52 = 1/2 chance first draw is red card, leaving 51 cards, of which 25 are red, so

25/51 chance second draw is a red card given the first one drawn is red.

probability both of the two cards drawn are red is 1/2 * 25/51 = 25/102.
