Probability of a red card out of 12 cards = 6/12 = 1/2
Now, probability of a red card of 11 cards = 5/11

Combined probability = 1/2 * 5/11 = 5/22

In short, Your Answer would be 5/22

Hope this helps!

He has 12 cards, half are black, and half are red.

Half would be 6, so

6 red cards
6 black cards

The probability of drawing a red card, is 50%. Same goes with a black card.

There fore, if you draw 2 cards, the probability of drawing two reds would be 25%.
