11/26 chance that the student plays both instruments.
First, add the amount of students that just play flute or piano:
3 + 5 = 8
Then add 8 to the amount that does not play either instrument:
8 + 7 = 15
Then do:
26 - 15 = 11
Then place 11 over the amount of people:
11/26

225 serves because you need to set up a proportion. The proportion is 2/5=90/x then solve for x by cross multiplying, which gives you 450=2x. Then divide 450 by 2 which gives you 225. Work shown in the attached picture.
