To find the probability of being dealt a diamond from a standard 52 card deck, we first need to determine how many diamonds are in the deck. A standard deck contains 52 cards, which includes 13 cards of each suit: hearts, diamonds, clubs, and spades.
Since there are 13 diamonds in the deck, we can calculate the probability using the formula for probability:
P(diamond) = (Number of favorable outcomes) / (Total number of possible outcomes)
Here, the number of favorable outcomes (the number of diamonds) is 13, and the total number of outcomes (the total number of cards) is 52. Thus, we can substitute these values into the formula:
P(diamond) = 13 / 52
This fraction simplifies to:
P(diamond) = 1 / 4
Therefore, the probability of being dealt a diamond from a standard 52 card deck is 1/4, or 25%.
