Math-New Question

posted by .

One card is selected from a deck of playing cards. Determine the probability of selecting:

a card greater than 9 or a black card

• Math-New Question -

26 black cards + 10 red cards above 9 = 36

Probability: 36/52 = 9/13

• Math-New Question -

Ms. Sue, number of cards greater than 9 = 4 (suits) * 4 (10, j, Q, K) = 16
but that includes the 8 black cards greater than 9 already counted in the black cards. What is the final answer? I'm lost :(

• Math-New Question -

You're looking for a card greater than 9 or a black card.

Which cards are considered greater than 9 depends upon the game you're playing. All of the games I play include the Ace as a high card.

ooooooh ok

• Math-New Question -

The number of cards greater than 9 or black= the number of cards greater then 9 + the number of black cards - the number of black cards greater then 9
=5*4 + 26 - 5*2=36
Probability=36/52

• Math-New Question -

what is the answer if the ace is considered a low card?
