Question

The Student Council advisor asked every tenth student in the lunch line how they preferred to be contacted with school news. Suppose there are 684 students at the school. How many can be expected to prefer E-mail?.

Answer 1

The number of students expected to prefer E-mail will be 68.

What will be the number of students expected to prefer E-mail?

It is given that

There are 684 students in the school

Every 10th student is preferred to be contacted

The number of the students to be contacted will be

$\rm N= \dfrac{Total\ students }{10}$

$\rm N= \dfrac{ 684 }{10}=68.4$

Here the number of the students will be 68.4 but we can only reach up to the 680th student and the other 10th student will at 690.

Thus the number of students expected to prefer E-mail will be 68.
