Answer:
C
Explanation:
The way to do this problem is to add all the choices together because that's the entire universe for that problem. That gives you 6 + 8 + 9 + 5 = 28. You have to take A ∩ Y which is 9. In other simpler words, you need to find a group that belongs to A and Y, That number is 9.
9/28 = 0.3214 (Edited) Thank you Jim
