the number of subsets 2^5=32

Answer 2

Thanks!
I knew it was something simple... And proper subsets?

Answer 3

the number of proper subsets i think its 2^5-1=31

Answer 4

Let A be a finite set having n elements. Then the total number of subsets of A is (2^n) and the number of proper subsets of A is (2^n−1)

Answer 5

I have no idea how I forgot that. Thanks so much.
