Question

write down the subsets of the following subsets: (i) Ø (ii) {2,7} (iii) {1,5,8}
please help​

Answer 1

(i) ∅

→ The only subset of ϕ is ϕ.

(ii) {2,7}

→ Empty set is a subset of every set

So,

The subsets of {2,7} are ϕ,{2},{7},{2,7}

(iii) {1,5,8}

→ Total number of elements is 3.

So ,

→ The subset will be

→ {1} {5} {8} {1,5} {1,8} {5,8} {1,5,8}

and { }.

Here,

“{ }” it means null.
