1. When you deal with complements, the first question to ask is
do we know the universal set E?

Here we assume E=Z (integers)

X'∩Y = Y\X = {10,20,40,60,90,100}
Y'&cup'Z'= YΔZ= {30,40,70,80,90,100}
(X\Z)'={10,20,30}' depending what E equals
(Y\Z)'∩X'
=((Y\Z)∪X)'
=({30,90,100}∪{10,20,30,40,50})'
={10,20,30,40,50,90,100}'
depending on what E is.

(note U cannot be the universal set because it does not contain any of the other members).

Note:
you can type
∩ as & c a p ;
∪ as & c u p ;
(do not enter interstitial spaces)
