Verified step by step guidance1
Step 1: Understand the problem by identifying the total number of possible outcomes. A standard deck of cards has 52 cards.
Step 2: Determine the number of favorable outcomes. There are 4 aces and 4 kings in a deck, making a total of 8 favorable outcomes.
Step 3: Use the probability formula: \( P(A ext{ or } K) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \).
Step 4: Substitute the values into the formula: \( P(A ext{ or } K) = \frac{8}{52} \).
Step 5: Simplify the fraction to find the probability of selecting an ace or a king from the deck.
