Answer:
Yes
Explanation:
Sure, this survey result could be correct. (2/3) x 24 = 16 students that said that they liked rap. This is a whole number, so sure, his survey result it possible.
(If he said that, for example, 1/11 of the class liked rap and there were 24 students, (1/11) x 24 = 2.18, and you can't have a fraction of a person for this type of survey result, so that wouldn't be a valid survey result!)
