Answer 2

Answer:

Three students' average marks is $25$.          

Explanation:

• In a particular list of numbers, their middle value is denoted by the average of the all of numbers in the list.
• Mode, mean and median are the three types of averages.
• We get the average of all the list of numbers by adding all the numbers divided by the count of list numbers.

The formula for average value is given as:

$Average=\frac{X1 +X2+...+Xn}{n}$

where $X1,X2...Xn$  are the value of numbers

           $n$ is the count of numbers.

Step 1:

Given marks of three students are $26,27$ and $22$.

So, $X1=26$

      $X2=27$

      $X3=22$

Sum total of the marks $=26+27+22$

                                      $=75$

Step 2:

Students' marks average is  $=\frac{75}{3}$

                                               $=25$

So, three students' average marks is $25$.
