Question

In a group of 25 girls, 8 ran for the cross country team, 13 are on the math league team, and 6 are on both teams. How many of the girls are not on either team?

Answer 1

10 girls are not on either team

Explanation:

first subtract 6 from 8 to get 2 (since it's easier) because those 6 girls are on the math league team as well

next add 2 and 13 to get 15

last subtract 15 from 25 to get 10

Answer 2

The number of girls that are not o either teams are 10.
