Question 1108867: If n(A) = 4, n(B) = 5, and n(C) = 6, what is the greatest and least number of elements possible in AᑎBᑎC?

Suppose:

A = {a,b,c,d}
B = (a,b,c,d,e}
C = {a,b,c,d,e,f}

Then AᑎBᑎC = {a,b,c,d} has a maximum of 4 elements.

Suppose:

A = {a,b,c,d}
B = (e,f,g,h,i}
C = {j,k,l,m,n,o}

Then AᑎBᑎC = Ø   (the empty set) has a minimum of no elements.
