Question

A bag contains three green marbles, four blue marbles, and two orange

marbles. If a marble is picked at random, what is the probability that an orange
marble will NOT be picked?

Answer 1

7/9

Explanation:

There are 9 marbles total. there are 3 green, 4 blue, and 2 orange. The chance of picking an orange is 2/9. The chance of picking a green is 3/9, or 1/3. The chance of picking a blue is 4/9. To find the chance of not picking an orange, add 3/9 and 4/9 to get 7/9. The chance of not picking an orange is 7/9. I hope this helps!
