Question 1206779: Let S be the universal set, where: S = {1,2,3,...,28,29,30}
Let sets A and B be subsets of S, where set A = {2,11,14,15,16,18,26}, Set B = {3,915,22,24,28}, Set C = {16,20,23,30}. List the elements for (AnBnC)

Let S be the universal set, where:
S = {1,2,3,...,28,29,30}
A = {2,11,14,15,16,18,26},
B = {3,9,15,22,24,28},
C = {16,20,23,30}.
List the elements for (A ∩ B ∩ C)
A ∩ B ∩ C= {x : x ∈ A , x ∈ B, and x ∈ C}
as you can see, there is NO elements in A, B and C which are common
(A ∩ B ∩ C)= { }

List the elements for (AnBnC)
~~~~~~~~~~~~~~~~~~
There is a FATAL ERROR in this post.
The number 915 can not be in the set B, since the number 915 is not an element of the universal set S.
