Question

Two classes of elementary school students were asked what activity they want to do during recess. Each student selects one recess option. The table summarizes the recess preference of each student in the class,

Answer 1

We want to evaluate the probability that,

a student selected at random prefers to play tag at recess. That can be written as;

`Pr(\text{Tag)}=\frac{No.\text{ of students who chose tag}}{Total\text{ number of students surveyed}}`

The number of students who chose tag is 9.

The total number of students surveyed is 40.

Therefore,

`Pr(\text{Tag)}=(9)/(40)`

Thus, the probability that, a student selected at random prefers to play tag at recess is 9/40
