A box is filled with 9 red crayons, 5 blue crayons, and 8 yellow crayons. A crayon is chosen at random from the box. Find the probability that it is a blue or a yellow crayon.

Answer 1

13/22

Explanation:

Total: 9 + 5 + 8 = 22

Blue or yellow: 5 + 8 = 13

P(Blue or yellow) = 13/22

Answer 2

13/22

Explanation:

The total number of crayons in the box

9 red crayons, 5 blue crayons, and 8 yellow crayons = 22

The number that are blue or yellow = 5+8 = 13

P (blue or yellow) = number that are blue or yellow / total

= 13/22
