Answer: (1) 12.9
Explanation:-
First 10 prime numbers  = 2, 3, 5, 7,11, 13, 17, 19, 23  & 29
The sum of the 10 prime numbers = 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29
= 129

Formula-
Average = the sum of the observation / the number of the observation

Then, the average of first ten prime numbers = 129/10
= 12.9

Hence, the answer is (1) 12.9.
