Answer:
12.5%
Explanation:
In order to get 9/72, you would use what's given to you in this problem. There are 20 red flowers, 43 pink flowers, and 9 yellow flowers. You would need to find the TOTAL amount population of flowers. You have to add 43 + 20 + 9. This adds up to 72 flowers. Now the problem has given you that 9 of the flowers are yellow. You are finding the probability of a flower being yellow, MEANING that you would have to compare it with the total amount (72). You will get 9/72 ! now you would have to divide 9 from 72, and you would get 12.5% !!~
I hope this helps ! ^^
