Mr. Green teaches band, choir, and math. This year, he has 57 students that take at least one of his classes. He teaches band to 25 students. There are 48 students who take either band or choir or both. There are 9 students who take both math and choir with Mr. Green. Use the Venn diagram below:
a. How many students take exactly 2 classes from Mr.Green?
Please help me figure this out...?
The venn diagram shows 7 in math in band...1 in only band...3 in all...17 in choir..

that's 11 in only band...sorry not 1

Total # of students = 57
Band students = 25
Band or Choir or Both students = 48
Choir and Math students = 9
So from what you stated in about the Venn diagram, it shows that only 7 students take exactly 2 courses from Mr. Green (Math and Band). So wouldn't it simply be 7 students?
