To Find :- A subset of {1,7,8} is ?
Solution :-
we know that, if a sets have n elements , then,
- Total number of subsets are 2^n .
so ,
→ set {1, 7, 8} = 3 elements .
then,
→ Total subsets are = 2³ = 8
and, these subsets will be :-
- { } = empty set or denoted by ∅ .
- {1}
- {7}
- {8}
- {1, 7}
- {1, 8}
- {7, 8}
- {1, 7, 8}
therefore, out of these 8 subsets we can write any subset in the answer . { since only 1 subset of set is asked. }
