1. The problem asks for the probability of drawing a black 7 from a standard deck of 52 cards. 2. A standard deck has 52 cards: 26 black cards (spades and clubs) and 26 red cards (hearts and diamonds). 3. There are two black 7s in the deck: the 7 of spades and the 7 of clubs. 4. Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes. 5. Therefore, the probability of drawing a black 7 is $$\frac{2}{52} = \frac{1}{26}.$$
