Answer:
The average number of cavities is 3.2
Explanation:
To find the answer we will put them in order from least to greatest.
0, 1, 4, 5, 6. Now add all the numbers up and we get 16. Because we are trying to find the average number, we will count up how many numbers there are. Since their are 5 numbers total, we divide 16 by 5 and we get 3.2. Therefore, 3.2 is our answer.
