A standard deck has *52 cards* divided into 4 suits: ♥ ♦ ♣ ♠
Each suit has *13 cards* — Ace to King
*26 red cards* (♥ ♦) and *26 black cards* (♣ ♠)
*Face cards* are Jack, Queen, and King (total 12)

Example: Probability of a face card = 12/52 = 3/13
Example: Probability of a red face card = 6/52 = 3/26
