What is the average of first five prime numbers?

Show answer & explanation

Correct answer: B

Explanation

The Correct answer is Option 2 i.e.  535\frac{3}{5}.

We know that,

Average = Sum of observations/Number of observations

First five prime numbers = 2, 3, 5, 7, 11

Average = (2 + 3 + 5 + 7 + 11)/5

⇒ 28/5 = 535\frac{3}{5}
