This is a probability case of statistics using the addition rule
P(A or B) = P(A) + P(B) - P(A and B).
The output can happen at the same time, for that reason it is not mutually exclusive. The output can be an ace and a black card.
first case: how many ace's we got=4 over the number of total cards=52
second case: how many black cards=26 over the total number of cards=52
BOTH cases: they can be just 2 cards that can be aces AND black.
(4/52)+(26/52)-(2/52)= 7/13=.538461538462= .5385
