I think not right

Answer 2

As we know, the number of subsets of any set is $2^{n}$, where n is the number of elements in that set.

every non-empty set has 2 subsets Ф and the set itself.

So,

    n(A) = 3

  ⇒ Number of subsets = $2^{n(A)}$

                                       = $2^{(3)}$

                                       = 8

The subsets of A are Ф and A, subsets of {A, B} are Ф,{A},{B},and { A, B},

the subsets of {1,2,3} are Ф, {1}, {2}, {3},{1, 2}, {2, 3},{1, 3},and {1, 2, 3}, the only subset of Ф is Ф.
