The sample is valid.
what percent of students prefer caramel popcorn?
We can make the following rule of three to answer this question:

27 ---> x
Clearing x we have:
x = (27/75) * (100)
x = 36%
36% percent of students prefer caramel popcorn

The prime number is 17 if you look at a multiplication chart there is nothing that equals 17 on there right ?? Even if you divide you will have to find something close to 17 like 16
