In this image, the question asks for the probability of selecting a king from a standard deck of cards.

A standard deck of cards contains 52 cards in total. There are 4 suits (hearts, diamonds, clubs, and spades), and each suit has one king. Therefore, there are 4 kings in a deck.

The probability of selecting a king is calculated as the ratio of the number of kings to the total number of cards:

$\text{Probability} = \frac{\text{Number of kings}}{\text{Total number of cards}} = \frac{4}{52} = \frac{1}{13}$

Thus, the correct answer is $\frac{1}{13}$.

Tip: In probability, when working with a deck of cards, always start by identifying the total number of possible outcomes (52 cards in a standard deck) and the favorable outcomes for the event you're calculating.
