Question

A = {1, 3, 2, 7} then write any three subsets of A.

Answer 1

We have,

A = {1, 3, 2, 7}

The three subsets of A are: {1}, {2} and {1, 2, 3}.

Disclaimer: There are 2⁴ = 16 subsets possible i.e. {}, {1}, {2}, {3}, {7}, {1, 2}, {1, 3}, {1, 7}, {2, 3}, {2, 7}, {3, 7}, {1, 2, 3}, {2, 3, 7}, {1, 3, 7}, {1, 2, 7} and {1, 2, 3, 7}.
