$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Given :

The numbers = 4.2, 3.8 and 7.6

To find :

The average (mean) of the given values

Solution :

Number of Observations = 3

Sum of Observations = 4.2 + 3.8 + 7.6

★ $\boxed{\sf{Mean = \frac{Sum \: of \: Observations}{No. \: of \: Observations}}}$

$\sf{\implies} \: \dfrac{4.2 + 3.8 + 7.6}{3}$

$\sf{\implies} \: \dfrac{15.6}{3}$

$\sf{\implies} \:5.2$

$\therefore$ The mean (average) of the given values is 5.2
