In a standard deck of 52 cards, the probability of drawing an Ace on a single random draw equals which fraction?

• A. 1/13
• B. 1/52
• C. 1/4
• D. 1/26

Answer: (A)

Probability here comes from counting how many favorable outcomes exist out of the total possible outcomes for one draw. There are 4 aces in a 52-card deck, so the chance of drawing an ace is 4 out of 52. That simplifies to 1/13, which is about 7.7%. The other fractions don’t fit this situation: 1/52 would be the chance of drawing a specific Ace (like the Ace of Spades) rather than any ace; 1/26 would imply two favorable cards out of 52, and 1/4 would imply 13 favorable cards out of 52, neither of which matches there being only 4 aces. So 1/13 is the correct probability.
