To determine the probability of selecting a heart card from a standard deck of 52 playing cards, we can use the basic formula for probability:
Probability (P) = Number of favorable outcomes / Total number of possible outcomes
In this case, the number of favorable outcomes is the number of heart cards, which is 13. The total number of possible outcomes is the total number of cards in the deck, which is 52.
Putting the numbers into the formula, we get:
P = 13 / 52
This fraction can be simplified by dividing both the numerator and the denominator by 13:
P = 1 / 4
Therefore, the probability of selecting one heart card on a single draw from the deck is 1/4, or 25%.
