Answer:

Step-by-step explanation:

Given that among 500 freshmen pursuing a business degree at a university, 315 are enrolled in an economics course, 213 are enrolled in a mathematics course, and 123 are enrolled in both an economics and a mathematics course.

From the above we find that

a) either economics of Math course is

[tex]315+213-123 =405[/tex]

Out of 500 students 405 have taken either Math or Economics

Hence

c) student who have taken neither = [tex]500-405 =95[/tex]

Exactly one course is either math or economics - both

= [tex]405-123 = 282[/tex]
