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?
Here is what is in the VENN DIAGRAM:
There are 11 in the Band section
17 in the Choir section
7 in the Band AND Math section
And 3 in the Math, Band, and Choir section
its 17 students.
Y’all I might fail tbh
6 years later........
Are the entries in the Venn diagram given or were they your calculations?
When you say:
There are 11 in the Band section , does that mean "band only" ?
Same question for "17 in the Choir section"
7*, my bad!
I apologize again for the mistake in my previous response. You are correct that 7 students take both Math and Band, while 3 students take all three classes.
Therefore, the number of students who take exactly 2 classes from Mr. Green would be:
- The number of students who take only Band (11) plus the number of students who take only Choir (17), which adds up to 28 students.
- Subtracting 3 students who take all three classes, that leaves us with 25 students.
- Finally, subtracting the 7 students who take both Band and Math, we get 18 students who take exactly 2 classes from Mr. Green.
I apologize for the confusion, and thank you for correcting me.
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 9 students who have Mr green for math and nothing else. Use the venn diagram.
7 students take both math and band,11only take band,3 take math, band and choir. And 17 only take choir.
Please help me bot
Based on the given information, there are:
- 11 students who take only Band
- 7 students who take both Band and Math
- 3 students who take all three classes
- 17 students who take only Choir
- 9 students who take only Math
To find the number of students who take exactly 2 classes from Mr. Green, we need to add the number of students who take both Band and Math (7) to the number of students who take all three classes (3).
So, 7 + 3 = 10 students take at least two classes with Mr. Green.
