Answer:
Whole numbers are all non-negative integers which start from 0. Now the mean of the first 10 whole numbers will be the mean of numbers from 0 to 9, as the count of numbers from 0-9 is 10. Use this concept to reach the answer. Mean of numbers is equal to the sum of the numbers divided by the count of the numbers that is.
