Question

List all the subsets of S. You may use "C" for chocolate, "V" for vanilla, and "M" for mint.

1. {}
2. C
3. V
4. M
5. CV
6. CM
7. VC
8. VM
9. MC
10.MV
11. CVM

Is this correct.

Answer 1

The order of elements in a set does not matter, so
VM and MV, MC and CM, and CV and VC are the same set.
So list those only once to get 8 subsets.
