Question
A friend offers you the following "friendly" gambling game. He'll draw two cards with replacement from a standard deck of 52 cards, then draw two more cards without replacement from a second deck of 52 cards. You are invited to place a bet on one of the two sets of two cards yielding two red cards. What should you do? A. Randomly select one of the two sets of cards, since you have the exact same probability of seeing two red cards in either case. B. Bet on the first set of two cards, since you have a higher probability of seeing cards in this set than you do in the other set. C. Bet on the second set of two cards, since you have a higher probability of seeing two red cards in this set than you do in the other set.Explanation / Answer
