Multiple Choice

If a single card is randomly selected from a deck of cards, what is the probability of selecting an ace or a king?

$0.0059$

$0.077$

$0.15$

$0.85$

Verified step by step guidance

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.
