(a) A ∩ U = Ø
(b) A ∪ U = 1
(c) Are A, V, and U mutually disjoint? Why or why not?
Yes, because the intersection of the sets A, V, and U is empty.
Yes, because no two of the sets A, V, and U have any elements in common.
Yes, because the union of the sets A, V, and U is empty.
No, because no two of the sets A, V, and U are disjoint.
No, because the sets A, V, and U are disjoint.
(d) n(A ∩ U) = 1
(e) n(A ∪ U) = 1
(f) A ∩ U = 1
(g) √8 ≠1
