Question

You are dealt one card from a​ 52-card deck. Find the probability that you are dealt a king or a red card.

Answer 1

7/13

Explanation:

Half the deck is red so there are 26 reds.

There are 4 kings but we already counted two of these in the 26.

So there are 26+2 red or king cards total.

The probability of selecting a king or red is 28/52.

This can be reduced by dividing top and bottom by 4: 7/13.
