Question : What is the average of the first six prime numbers?
Option 1: $6 \frac{1}{3}$
Option 2: $6 \frac{5}{6}$
Option 3: $6 \frac{2}{3}$
Option 4: $6 \frac{1}{6}$
Correct Answer: $6 \frac{5}{6}$
Solution : First six prime numbers = 2, 3, 5, 7, 11, 13 ⇒ Average = $\frac{\text{Sum of numbers}}{\text{Frequency}}$ $=\frac{2+ 3+ 5+ 7+ 11+ 13}{6}$ $=\frac{41}{6}$ $= 6 \frac{5}{6}$ Hence, the correct answer is $6 \frac{5}{6}$.
