One card is selected from a deck of playing cards. Determine the probability of selecting:
a card greater than 9 or a black card.
hmmmmm....i don't play cards, i'm not even sure how many is in a deck...38??

Ms. Sue,
A deck of cards has 52 cards  13 in each of four suits.
Two suits are red: hearts and diamonds
Two suits are black: clubs and spades
The cards in each suit (in order): 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace. 
Math 
Jen,
oh thank you Ms. Sue....so the probability would be 31/52 or 0.596??
