A universal set U consists of 26 elements. If sets A, B, and C are proper subsets of U and n(U)equals=26, n(A intersect∩ B)=n(A intersect C)=n(B intersect C)=10, n(A intersect B intersect C)=4, and n(A union B union C)equals=22, determine each of the following.(a) n((A u B u C)') and (b) n(A' intersect B' intersect C).
