In a school of 464 students, 89 students are in the band, 215 students are on sports teams, and 31 students participate in both activities.
How many students are involved in neither band nor sports?
A.160 students
B.191 students
C.249 students
D.433 students
I think it is A...?

I didn't get A,
Did you make a Venn Diagram with two overlapping circles.
The 31 goes in the overlap. for band alone subtract the 31 from 89. For the sports alone subtract the 31 from 215.
Add up all of the numbers in the 3 parts of the circles and subtract from 464. 
Thank you
