Would I do something like this:

1. {}
2. Math

4. history
5. science
6. art
7. Math and English
8. math and history
9. math and science
10. math and art
and so on.

Answer 1

square root of 5 over 5

Answer 2

I am not sure I understand what you are saying; however, would my answer be 25?

Answer 3

I don't know about the subsets, but Isaiah's answer is unclear.

If it is √(5/5) = √1 = 1

If it is (√5)/5 = 2.2361/5 = .44722
