Question

If you choose one card from a standard deck, what is the probability that the card is either red or a king? A) 3 13 B) 5 13 C) 7 13 D) 9 13

Answer 1

7/13

Explanation:

Half the cards are red. There are 4 kings, 2 of which are black cards. So the probability is:

P = (26 + 2) / 52

P = 28 / 52

P = 7 / 13
