The way you have this written, the smallest class would be 17 (since it has to be more than 16) and the largest would be 28 (since you can have less than or equal to 28). All the possible options would be the set {17, 18, 19, 20, 21, 22,23,24,25,26,27,28}
But does the problem give you a total number of students to distribute?
