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

Understand the problem: We need to find the probability of drawing either an ace or a king from a standard deck of cards.

Identify the total number of possible outcomes: A standard deck has 52 cards.

Determine the number of favorable outcomes: There are 4 aces and 4 kings in a deck, making a total of 8 favorable outcomes.

Use the probability formula: Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Calculate the probability: Substitute the values into the formula to find the probability of drawing an ace or a king.
