Many questions come up in probability involving a standard deck of playing cards. Furthermore, many times card players will also want to know different probabilities for the card games they are involved in.
In this post, you will learn about probability with a deck of cards and how it works. This will include examples of probability with cards, and also how many ways a deck of cards can be shuffled and arranged. Finally, common playing card probability questions will be answered.
The 52 cards in the deck are divided into 4 suits. These suits are the Hearts, Diamonds, Clubs and Spades. The Hearts and Diamonds are the red suits. The Clubs and Spades are the black suits.

Face Cards in Probability
There are 12 face cards in a deck of 52 cards. (To learn more see Face Cards in a Deck) This means that the odds of drawing a face card will be 12/52, or 3/13.
The odds of drawing a non-face card will be the opposite of this, or 40/52, which simplifies to 10/13.
There are 6 red face cards and 6 black face cards in a deck. This means the odds of drawing a red face card are 6/52 or 3/26. The odds of drawing a black face card are the same, 3/26.
