To find the probability of being dealt a diamond from a standard 52-card deck, we start by understanding the composition of the deck. A typical deck consists of 52 cards, which are divided into four suits: hearts, diamonds, clubs, and spades. Each suit contains 13 cards.
Since we are interested in the probability of receiving a diamond, we focus on the diamonds in the deck. There are a total of 13 diamond cards.
The probability formula is given by:
Probability (P) = Number of favorable outcomes / Total number of possible outcomes
In this case, the number of favorable outcomes (the number of diamonds) is 13, and the total number of possible outcomes (the total cards in the deck) is 52. Plugging these values into the formula gives us:
P(diamond) = 13 / 52
Now, simplifying this fraction:
P(diamond) = 1 / 4
Therefore, the probability of being dealt a diamond from a standard 52-card deck is 1/4 or 25%.
