Let AB, and C be subsets of a universal set U and suppose n(U) = 100, n(A) = 26, n(B) = 28, n(C) = 32, n(A ∩ B) = 6, n(A ∩ C) = 9, n(B ∩ C) = 14, and n(A ∩ B ∩ C) = 4. Compute:

 n[A  (B  C)]


  n[A  (B  C)c]

Can someone help me solve this I keep getting 15 and 28 I don't know what im doing wrong
