Absolute risk is defined as the proportion or percentage of people in a group for whom an undesirable event occurs.

In a math class, there were 20 students who sat in the back and 20 students who sat in the front. Of those who sat in the back, 9 students failed the class. Of those who sat in the front, 3 students failed the class.

Calculate the absolute risk of failing the class for students who sat in the back and for students who sat in the front. Give your answers as fractions, proportions, and percentages.

Answer :

Given in the scenario:

a.) 9 of the 20 students who sat in the back failed the class.

b.) 3 of the 20 students who sat in the front failed the class.

A.) The absolute risk of failing the class for students who sat in the back.

In the back, 9 of the 20 students who sat in the back failed the class.

The absolute risk in proportion = 9:20

The absolute risk in fraction = 9/20

The absolute risk in percentage = (9 ÷ 20) x 100 = 0.45 x 100 = 45%

B.) The absolute risk of failing the class for students who sat in the front.

In the front, 3 of the 20 students who sat in the front failed the class.

The absolute risk in proportion = 3:20

The absolute risk in fraction = 3/20

The absolute risk in percentage = (3 ÷ 20) x 100 = 0.15 x 100 = 15%
