What is the probability that when playing cards you will get a spade, or a red card.?

Since your question is the probability of getting a spade "or" a red card the correct answer is 3/4. The reason is that 1/4 of the deck is diamonds (red), and 1/4 are hearts (red), and then 1/4 are spades. The key in the question is "or."

What is the probability that when playing cards you will get a spade, or a red card.?
52 cards in a deck.


13 Spades = 13/52 reduced = 1/4


26 red cards (hearts and diamonds)=26/52 reduced = 1/2
Reply:I think it's 3/4. the only cards that wouldn't be a spade or red would be clubs, which is 1/4 of the deck.
Reply:chance you get a spade =1/4


chance you get a red = 1/2


multiply them together for your answer.
