Problem:
Let A, B and C be subsets of a universal set U and suppose n(U) = 100, n(A) = 30, n(B) = 30, n(C) = 32, n(A ∩ B) = 9, n(A ∩ C) = 10, n(B ∩ C) = 14 and n (A ∩ B ∩ C) = 5.
Compute n(AC ∩ BC ∩ CC).
a. 39
b. 14
c. 10
d. 70
e. 89
f. 64
Additional Information:
This question is from Mathematics as well as it is about determining the intersection of all the subsets.
