Geometry Probability

Question

What is the probability of randomly drawing 1 card that is a black card, or an ace card, or both, out of a standard deck of 52 playing cards?

Enter your answer as a fraction, using the / symbol, like this: 5/14

Answer 1

There are 26 black cards and 4 aces. Since two of the aces are black you need to subtract 2 from the sum since their is repetition. The probability is then 28/52 = .5385 which is about 58.9%.
