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.`
