a: C
b: B
c: A
If A is the set of 4-digit multiples of 2, B is the set of 4-digit multiples of 5, and U is the set of all 4-digit numbers, express using union, intersection, and complement notation:
a: Set C of 4-digit multiples of both 2 and 5
A) C=U\(A∪B)
B) C=(A∪B)∩U
C) C=(A∩B)∩U
D) C=A∪(B∩U)
b. Set D of 4-digit multiples of at least one of 2 or 5
A) D=U\(A∪B)
B) D=(A∪B)∩U
C) D=(A∩B)∩U
D) D=U\(A∩B)
c. Set E of 4-digit numbers that are neither multiples of 2 nor multiples of 5?
A) E=U\(A∪B)
B) E=U\(A∩B)
C) E=U∩(A\B)
D) E=A∩B∩U
