One card is randomly selected from a standard deck of 52 cards. What is the probability of randomly selecting a(n) King or Ace? Enter your answer as a reduced fraction.

A standard deck of 52 cards has four suits: hearts, diamonds, clubs, and spades. Each suit contains 13 cards, including one King and one Ace. 

To find the probability of randomly selecting a King or an Ace, we need to count the total number of Kings and Aces in the deck:

1. **Number of Kings:** There are 4 Kings in a deck (one for each suit).
2. **Number of Aces:** There are 4 Aces in a deck (one for each suit).

The total number of Kings or Aces in the deck is:

\[
4 + 4 = 8
\]

Now, the probability of an event is given by:

\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}
\]

Here, the number of favorable outcomes is 8 (the Kings and Aces), and the total number of possible outcomes is 52 (all the cards in the deck).

So, the probability of randomly selecting a King or an Ace is:

\[
\frac{8}{52}
\]

To reduce this fraction, we find the greatest common divisor (GCD) of 8 and 52, which is 4. Now, divide both the numerator and the denominator by 4:

\[
\frac{8 \div 4}{52 \div 4} = \frac{2}{13}
\]

Thus, the probability of randomly selecting a King or an Ace from a standard deck of 52 cards is:

\[
\boxed{\frac{2}{13}}
\]
