Question

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

Answer 1

The correct option is B

$6.83$

The explanation for the correct option.

Find the mean of the first six prime numbers.

The first six prime numbers are $2,3,5,7,11,13.$

$$\begin{gathered} \mathrm{Mean}=\frac{\mathrm{Sum}\mathrm{of}\mathrm{elements}}{\mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{elements}} \\ \mathrm{Mean}=\frac{2+3+5+7+11+13}{6} \\ \mathrm{Mean}=\frac{41}{6} \\ \mathrm{Mean}=6.83 \end{gathered}$$

Therefore the mean is $6.83$.

Hence option $B$ is the correct answer.
