a) AUD =

b) B∩C =

c) A∩D =

d) (BUC) ∩D =

e) (CUD) ∩A =

f) ( BUD) ∩C =

Answer 1

a) AUD = {{∅},0,1,2,6,9,15,20}
b) B∩C = {{∅}}
c) A∩D = {{∅}}
d) (BUC) ∩D = {{∅},1,3,7,10,11,15,20,30} ∩D ={{∅},1,15,20}
e) (CUD) ∩A = {{∅},1,15,10,20,30} ∩A = {{∅}}
f) ( BUD) ∩C = {{∅},1,3,7,11,15,20} ∩C = {{∅},20}
