Answer:
6 Orange picks
Step-by-step explanation:
All I did was I used trial and error. Since I know that the number would be too big if I said there were 20 green, I tried 15 green. Sure enough, that was the correct answer. 5 times 3 is 15, so you would need to do 2 times 3. The answer is 6 orange picks.
