A little help needed in Sets Question!

[nabeel LS7]

Out of a group of 25 girls, 15 play netball, 10 play rounders and 4 play neither netball nor rounders. Find the number of girls who play rounders but not netball?

Help will be appreciated!

Just make a Venn Diagram, will make it easy.

So the answer is 6.

the steps for doing this is:
let the number of netball and rounders intersection be x.
so the total number of netball players minus x, the total number of rounders minus x, x and number of girls that are neither add up to 25.
15 - x + 10 - x + x + 4 = 25
29 - x = 25
29 - 25 = x
x = 4
subtract the value of x from the total value of rounders to get the answer for girls who play rounders only.
so 10 - 4 = 6
