What is the probability of drawing a King if spades from a standard deck of cards?

The total number of all possible outcomes is 52 since there are fifty-two different cards in a deck. The number of outcomes favorable to drawing a King of spades is 1 as there is only one of this type of card.

$\therefore$ Applying the formula:

\[
P_{\text{King of Spades}} = \frac{\text{Number of Outcomes Favorable to King of Spades Turning Up}}{\text{Number of all Possible Outcomes}}
\]
\[
P_{\text{King of Spades}} = \frac{1}{52}
\]
\[
P_{\text{King of Spades}} = 1.92\% \leftarrow \text{answer}
\]
