Will fan and medal, please!
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. Here is what the Venn diagram is like:

Total = 57
Band = 25 but on the Venn it shows 21
Band and or choir = 48 but the Venn shows 41
Choir = 20 but 17 ONLY take choir
Math and choir = 9

How many students take exactly 2 classes from Mr. Green?
