Count how many sets have no elements: the empty set {}.
Now how many sets have one element?
How many have two? (hint: it's the same as the number of 1-element sets)
How many have three?

the number of subsets is always 2n where n=# of elements in the set
since there are three elements in the set, 23=2*2*2=8 subsets
