Heyhey, can someone please help me with this question?
The universal set, U and the two sets A and B cantained within are such that:
-n(AnB)=6
-n(A)= 27
-n(B)=46
-n(U)=70
determine 1) n(AuB) 2) n((AuB)')
I have so far found out that A,B and AnB don't add up to 70, how do you work out the actual number of A and B?
thank you xxx
