Answer:

It would not be a random fair sample, as the sample categories each should be 30 minimum for such sample tests to be effective. There are 20 cities so the maximum any category group can be sampled is 3 per city and 2 from other cities as 50/2 = 25 = 2.5 each. Therefore by having data from other cities this creates 20 other categories as the samples are based on geographic wider scale such survey would require 30 from each city to show effectiveness and it would require reliable data of 30 from from each city instead of 2-3 each city.

A campus radio station surveyed 500 students to determine the types of music they like. the survey revealed that 199 like rock,
Ostrovityanka [42]
<span>There are 24 who like both rock and country. There are 8 who like all 3 types, and these eight have been counted under the 24. This means that the number who like rock and country but not jazz is 24 - 8 = 16.
We are given a total of 155 who like country. We subtract the 16 who like both rock and country, and are left with 139 people who like country but not rock. (It does not matter whether they like jazz or not).
The probability is 155 out of the total of 500, so 155/500 = 31/100 = 0.31.
