A bag contains 7 blue marbles, 5 red marbles, and 9 green marbles. A marble is taken at random from the bag. What is the probability that the marble is blue or red? Please check my answer 12/21

its right but simplify it and you get 4/7 that's the answer good job

I agree with Jen's answer, it is 12/21 or 4/7

A marble is randomly selected from a box containing 5 green,3 red and 7 blue marble?
