A standard deck of playing cards has 52 cards in total, consisting of 26 red cards (hearts and diamonds) and 26 black cards (clubs and spades).
In the deck, there are two black nines: one from clubs and one from spades.
To find the probability of drawing a black nine, you can use the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
Here, the number of favorable outcomes (black nines) is 2 and the total number of outcomes (total cards) is 52:
\[ \text{Probability} = \frac{2}{52} = \frac{1}{26} \]
So, the correct response is:
