Question 374978: One card is randomly selected from a deck of 52 cards. Find the probability of selecting a black card or a prime digit card. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! There are 26 black cards, 26 red cards.
The prime number cards are the 2,3,5,and 7 (not counting the Jack as 11).
Since the black 2, 3, 5, and 7 are already counted in the black cards, only count the red ones (diamonds and hearts).
