In a class of 50 students, 18 take music, 26 take art, and 2 take both art and music. How many students in the class are not enrolled in either music or art?

Correct Answer: 8
50 - 18 - 26 + 2 = 8, as 2 take both art and music , we need to add them, as they get subtracted twice while subtracting 18 and 26 from 50.
