Thank you!

Out of 52 cards (no jokers), half of them (26) are red, and 4 are queens. However, 2 of the queens are red anyway so don't count them twice. So there are 28 cards out of 52 that you want.

So the probability is or 53.8%

Hope I helped you

Hi PiratePrincess,

There are 26 red cards, 2 of which are queens.
There are 4 queens, 2 of which are red.
There are 2 non-red (black) queens.

The probability is the sum of the probabilities of drawing a red card and the probability of drawing a black queen.
Or it is the probability of drawing a red queen subtracted from the sum of the probability of drawing a red card and the probability of drawing a queen (since both of those contain the probability of drawing a red queen).

I really appreciate your help!
I have my first test on probability tonight, wish me luck!

Your welcome and good luck!!

just remember these stats. There are 52 cards in a deck. Half of those are red. there are four of each kind of card they are: Ace 2 3 4 5 6 7 8 9 10 Jack queen King.
there are sometimes jokers beware.
