Probability: In a standard deck of 52 cards, what is the probability of drawing an Ace on a single draw?

• A. 1/52
• B. 1/26
• C. 1/10
• D. 1/13

Answer: (D)

Probability is found by dividing the number of favorable outcomes by the total number of possible outcomes. In a standard 52-card deck, there are 4 aces, so the chance of drawing an Ace on one draw is 4 out of 52, which simplifies to 1/13. That matches the correct choice. In decimal terms, it’s about 7.69%, which fits the idea that roughly one in every thirteen cards would be an Ace if you drew many times. The other options don’t fit because they imply a different count of favorable cards or a different total: 1/52 would mean only one Ace in the deck; 1/26 would mean two Aces; and 1/10 suggests ten percent, not the actual ratio of 4 to 52.
