What is the average of the first six prime numbers?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 656\frac{5}{6}. 

The first 6 prime numbers are 2, 3, 5, 7, 11, 13

Sum = 2 + 3 + 5 + 7 + 11 + 13 = 41

We know that,

Average = Sum of observations/Number of observations

Average = 41/6 = 6566\frac{5}{6}
