    Probability = 2/13 ≈ 15.4%

    Step-by-step explanation:

    We are looking for probability of drawing an ace or king from a standard deck of cards.

    In a standard deck of cards, there are 4 ace and 4 king.

    4 + 4 = 8, this is the number of possible "correct" cards you can draw, which satisfy the conditions.

    Since a standard deck has 52 cards, this is the number of cards you can draw, the "possible outcomes".

    Probability is the number of "correct" outcomes divided by the total possible outcomes.

    The probability is 8 / 52, but we need to reduce the fraction.

    Both numerator and denominator are divisible by 4.

    8 / 52 = 2 / 13

    If you want the probability as a percentage, divide 2 by 13 and multiply by 100.

    Probability = 2/13 ≈ 15.4%
