D.
Cannot be determined as the sets $$A$$ and $$B$$ are not given
Answer :
Cannot be determined as the sets $$A$$ and $$B$$ are not given
Solution :
Given, $$n\left( A \right) = 4,\,n\left( B \right) = 3$$
Since, the sets $$A$$ and $$B$$ are not known, then cardinality of the set $$A\Delta B$$ cannot be determined.
