Question

Mean of first six prime numbers is _________.

• A. $4.83$
• B. $6.83$
• C. $5.83$
• D. $7.83$

Answer 1

Answer: (B)

$6.83$

First six prime numbers are $2,3,5,7,11$ and $13$.

Then, the number of elements $=6$.

We know, Mean is given by,

$\text{Mean}=\frac{\text{Sum of the elements}}{\text{Total number of elements}}$.

Therefore, Mean $=\frac{2+3+5+7+11+13}{6}=\frac{41}{6}=6.83$.

Hence, option $B$ is correct.
