Find the number of subsets of the given set. {math, English, history, science, art}
Is this correct:
1. {}
2. {math}
3. {English}
4. {history}
5. {science}
6. {art}
7. {m, E}
8. {m,h}
9. {m, s}
10. {m, a}
11. {e, h}
12. {e, s}
13. {e, a}
14. {h, s)
15. {h, a}
16. {s, a}
17. {m, E, h, s, a}

if a set has n elements there will be 2^n subsets.
Yours should have 32 subsets.
You are missing all the triples and fours.
