EXAMPLE 3.1.2

The graph below shows the distribution according to academic major of a group of students. None of them have double majors.

Approximately what percent are majoring in something other than music?

A. 25%

B. 12%

C. 88%

D. 94%

SOLUTION

First find the total number of students:

60+12+80+35+25 = 212

Among these 212 students, those who aren't majoring in music number

60+80+35+25 = 200.

Finally, 200/212 = .9434 = 94.34%

The best choice is D.
