Question

A={1,3,2,7}than write any four subsets of A​

Answer 1

Step-by-step explanation:

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}.

The elements of set A are 1,3,2 and 7. There are 4 elements of A. It would mean that possible subsets are 2⁴ or 16.

So, the three subsets are as follows :

{1,2}, {2,3} and {3}.

Hence, this is the required solution.
