Question 387786: How many subsets does the set {A,B,C,D,E} have?

For any subset S, we can choose which elements belong in S. This means:

A is in S or A is not in S
B is in S or B is not in S
.
.
.
E is in S or E is not in S

Each case has 2 possibilities, so the total number of subsets (including the empty set and {A,B,C,D,E}) is 2^5, or 32.
