Subset Algebra

Question

{a,e,i,o} List all the subset of each set

Answer 1

Since the set has 4 elements, the number of subsets is 2⁴ = 16. Two of the subsets are the empty set and the set itself. The other subsets are:

{a}, {e}, {i}, {o}, {a,e}, {a,i}, {a,o}, {e,i}, {e,o}, {i,o}, {a,e,i}, {a,e,o}, {a,i,o}, {e,i,o}
