Answer:
a) {15}
b) { }
c) D or {5, 7, 8, 12, 13, 15}
d) no
e) yes
Step-by-step explanation:
a) AUB: even or prime
D - (AUB) = {15}
b) AUC: even or odd; basically all integers
D - (AUC) = { }
c) A∩B : even and prime, that's only 2
D - (A∩B) = {5, 7, 8, 12, 13, 15} = D
d) A and B, both contain 2
Not disjoint
e) A and C are disjoint because no number can be both, even and odd
