Question

Suppose fifty students take at least one class from Mr. Green, who teaches band,

choir, and math. Use the Venn diagram. How many students take exactly 2 classes
from Mr. Green?

Answer 1

13

Explanation:

7 students take band and math only

2 students take band and choir only

4 students take choir and math only

We do not include the students that take 3 classes because it says exactly 2 classes

7+2+4 = 13
