What is the probability of drawing an ace from a standard deck of cards?

To determine the probability of drawing an ace from a standard deck of 52 playing cards, we first need to identify how many aces are in the deck. A standard deck contains four aces—one for each suit (hearts, diamonds, clubs, and spades).

The probability of an event is calculated using the formula:

[

\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}

]

In this case, the number of favorable outcomes (drawing an ace) is 4, and the total number of possible outcomes (the total number of cards in the deck) is 52.

So the probability of drawing an ace can be calculated as:

[

\text{Probability of drawing an ace} = \frac{4}{52}

]

This simplifies to:

[

\frac{4}{52} = \frac{1}{13}

]

Thus, the correct answer is the probability of drawing an ace is 1/13. This means that out of the 52 cards, 1 in every 13 cards you draw is expected to be an ace, affirming the answer provided.
