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.

A deck has 52 cards, it is divided into diamonds, spades, hearts and clubs, each group has 13 cards, and together they make up 52 cards. Now the question asked is one card has been dealt out of 52, what is the probability that it is a diamond?

Total cards= 52

diamonds= 13

probability= 13/52

= 1/4

It has a probability of 1/4 or 0.25 or 25% that a diamond card will be dealt.
