.
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)

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.
