At Highschool, students have 3 science class options - A,B,C (names dont matter, they're like biology and physics and stuff).84 students are taking A, 116 are taking B and 58 are taking exactly 2 out of the 3 classes. One student is taking A,B, and C. How many students are in at least 1 of the 3 classes?

I got the wrong answer and am not sure why :\

Thanks a lot :]
