Let us take the set A = {1, 2}

Let us find all the subsets of A


We know from property of subsets that

  • Empty set is the subset of all sets
  • Every set is a subset of itself


So, subsets of A will be


{1}, {2},

{1, 2}


Power set is the set of all subsets.

So, we write power set of A as

P(A) = {∅, {1}, {2}, {1, 2}}
