Question

Suppose that among the 220 students registered in CS 361, there are 185 students that have taken both a calculus and a linear algebra class in the past, and there are 5 students that have taken neither. How many students have taken at least one of those two math classes in the past

Answer 1

215 students have taken at least one of the two math classes

Explanation:

Since there are 220 students and 5 students have taken neither calculus nor linear algebra,

that leaves us with 220-5 = 215 students who have taken at least one of the two math classes
