Explanation

A standard deck has 52 cards, containing 4 kings and 4 queens. The probability of drawing a king or a queen is the sum of their individual probabilities, which is (4 + 4) / 52 = 8 / 52 = 2 / 13.

AI explanation

A standard deck of 52 playing cards contains exactly 4 kings and 4 queens, meaning there are 8 favorable outcomes for this event. The probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes, which is 8 divided by 52. Simplifying this fraction by dividing the numerator and the denominator by 4 gives the result 2/13.
