Question

A=(a b c d) write down subsets of A???.?

Answer 1

these are subsets of set A={a,b,c,d}

Answer 2

Answer:

The list of all subsets of a,b,c,d is ϕ ,{a},{b},{c},{d},{a,b},{a,c},{a,d},{b,c},{b,d},{c,d},{a,b,c},{a,b,d},{a,c,d},{b,c,d},{a,b,c,d}

Step-by-step explanatA subset of a set is the same thing as choosing which elements from your original set you are going to keep, and which ones that you do not.

So if you have a set with  n  elements then there are  2n  possible subsets.

For the given set  A={a,b,c,d}  there are  4  elements so there are  24=16  possible subsets.

Hope it helps you !
