Your mom is a sporting person, so when it's close to your bedtime, she will have a contest with you to see if you get to stay up and extra half-hour to play a computer game. You get to draw a card from a well-shuffled deck. If you draw a face card, an ace, or any heart, she'll "have a heart" and let you stay up. If you draw any other card, you lose and go ahead to bed. Who has the best chance of winning, you or your Mom?
The person with the most qualifying cards in the deck has the best chance. There are 12 face cards and 4 aces. There are also 9 hearts that are not aces or face cards. You can only win with 25 cards out of 52. That is less than half the deck.
