Asurvey was conducted in which a random sample of 1,000 people were asked to pick their favorite type of music. the top three were:

pop 30%
rock 26%
country 20%

how many of the people surveyed did not like any of the top three types of music?

Given:
sample population: 1,000

Pop = 30% = 1000 x 30% = 300
Rock = 26% = 1000 x 26% = 260
Country = 20% = 1000 x 20% = 200

1000 - 300 - 260 - 200 = 240

or:
100% - 30% - 26% - 20% = 24%
1000 x 24% = 240

There are 240 people surveyed that do not like any of the top three types of music.
