What is the probability that the card drawn is a black card or an ace?

7/13

Step-by-step explanation:

The question asks for the probability of drawing a black card or an ace. When it says or, we know that we need to add the two probabilities.

The probability of drawing a black card is 26/52, because half the cards are black.

The probability of drawing an ace is 4/52, because there are four aces.

But wait! We can't double-count. Two of those aces are black, so we need to subtract by 2/52.

26/52 + 4/52 = 30/52 - 2/52 = 28/52

28/52 = 7/13
