Answer 2

Given :

First 10 prime numbers which are odd.

To Find:

Average of first 10 prime numbers which are odd

Solution:

The first 10 odd prime numbers are 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31.

Sum of the odd prime numbers = (3+5+7+11+13+17+19+23+29+31)

                                                    = 158

Number of odd prime numbers = 10

We know, Average = (sum of the 10 odd prime numbers ÷ Number of odd

                                   prime numbers)

                Average = $\frac{158}{10}$

                               = 15.8

∴ The Average of first 10 prime numbers which are odd is 15.8
