Suppose you draw a card from a standard deck. What is the probability of selecting a King or an even valued-card?

You may answer with a fraction or a decimal rounded to three places.

A standard deck of cards contains 52 cards, which include:

- 4 Kings (one from each suit).
- Even-valued cards: The even-valued cards are 2, 4, 6, 8, 10. There are 4 cards for each even value (one from each suit), so there are \( 5 \times 4 = 20 \) even-valued cards.

Now we need to find the total number of cards that satisfy the condition of being either a King or an even-valued card. There are:

- 4 Kings.
- 20 even-valued cards.
  
However, there is no overlap between Kings and even-valued cards, so we simply add the two sets:
\[
4 + 20 = 24
\]

The total number of possible outcomes is 52 cards, so the probability is:
\[
\frac{24}{52} = \frac{6}{13} \approx 0.462
\]

Thus, the probability of selecting a King or an even-valued card is approximately \( 0.462 \).
