Answer:
83.333…
Step-by-step explanation:
In order to find the answer, you need to add 76+84+90.
You would get 250.
You would need to divide it by 3 because the student has only done 3 tests so far so you would get 83.333….
So, the possible value that the student might get in his fourth quiz is 83.333…
Hope this helps:)
