Question

The total number of subsets of {A,B,C} is ?

Answer 1

The total number of subsets that can be derived from the given set is given by the formula 2 n where n is the number of elements present in the set.Here in the given set n=3

Number of subsets = 2 3    = 8 subsets are formed.

Answer 2

Remember, the number of subsets of a set is 2$2^n$, where n is the number of elements in the set. Thus, it is 2³ = 8. If you want a proof for that, ask in comments below.
