Question

In a group of 120 band students 30 of them play a woodwind instrument. What percent of the band students do not NOT play a woodwind instrument.

Answer 1

Answer: 75%

Explanation:

We are told that in a group of 120 band students 30 of them play a woodwind instrument. The number of those that don't play woodwind instrument would be:

= 120 - 30 = 90

The percent of the band students that do not not play a woodwind instrument will be:

= 90/120 × 100

= 3/4 × 100

= 75%
