A standard deck of playing cards contains 52 cards, which includes 2 black nines (the 9 of spades and the 9 of clubs).
The probability of drawing a black nine from the deck can be calculated as follows:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{2}{52} = \frac{1}{26} \]
Therefore, the correct response is:
Start Fraction 1 over 26 End Fraction.
