(some of these may have also taken geometry, logic, or geometry and logic),
11 had taken geometry
(some of these may also have taken algebra, logic, or algebra and logic),
9 had taken logic
(some of these many also have taken algebra, geometry, or algebra and geometry),
6 students had taken both algebra and logic and geometry
(some of these may also have taken logic),
5 students had taken both algebra and logic
(some of these may also have taken geometry),
10 students had taken exactly two of these courses, and 2 students had taken all three courses.
How many students had taken exactly one of these courses.
