Answer
$\frac{1}{13}$
Work Step by Step
Total number of cards or outcomes = 52
Probability = $\frac{Total outcomes}{favorable outcomes}$
For finding probability of dealing a red 7 or a black 8, favorable outcomes = 2 + 2 = 4
Probability of dealing a red 7 or a black 8 = $\frac{4}{52}$ = $\frac{1}{13}$
