Question

A bag contains 7 red marbles, 12 orange marbles, 18 yellow marbles, and 5 purple marbles. A marble is drawn at random from the bag.

What is the probability that the marble drawn will not be orange?

Answer 1

5/7 is your answer.
Hope this has helped

Answer 2

7+12+18+5=42 total marbles
42-12 to get non orange marbles
(30/42)*100= probability of not getting an orange
.714*100= 71.4% if asked for percent or 5/7 if fraction
