What is the probability of drawing a red card or a queen from a deck of cards?
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 $\displaystyle \frac{28}{52} = \frac{7}{13} \approx 0.538$ 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).
