Calculate the probability of being dealt a diamond from a standard deck of 52 cards.

Since there are 4 suits in a deck of cards (hearts, clubs, spades and diamonds) we can find the number of diamonds in the deck by:

52÷4 = 13

There are 13 diamonds in a deck of cards. Therefore, the probability of being dealt a diamond is 13 possible diamonds out of 52 cards.

`13/52 = 1/4`

**Therefore, the probability of being dealt a diamond is `1/4.`**

Probability is 13/52, or one in four, or 25%. The "math" is simply the number of cards that fit the description "diamond" over the total number of cards or chances available.
