Yanıt Açıklaması:

If A is a finite set and n is the number of its elements, that is s(A) = n, then the number of all subsets of A is 2ⁿ.

For example, if A = {1, 2, 3} then the subsets of A

are Ø, {1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, {1, 2, 3}.

The set A has 2³ = 8 subsets. Recall that, by convention, every set is its own subset, that is A ? A. The empty set Ø is a subset of any set.

As also understood from the information given the subsets of A are

Ø, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c}, so the correct answer is E.
