The Venn diagram shows a universal set, $$\(\mathscr{E}\)$$ and sets $$\(A, B\)$$ and $$\(C\)$$. $$\(12,5,9,10,6,3,4\)$$ and 8 represent the numbers of elements. Find (i) $$\(\mathrm{n}(A \cup B)\)$$ (1) (ii) $$\(\mathrm{n}\left(A^{\prime} \cap B^{\prime}\right)\)$$ (1) (iii) $$\(\mathrm{n}([A \cap B] \cup C)\)$$
