Answer:
A = set of even integer numbers.
B = set of odd integers.
C = prime number set
D = integers which are multiples of 3.
A - B = A - A Π B = A
as A and B are disjoint sets. A Π B = null set φ
B - A = B as same reason as above.
A U B = I or Z = set of all integers , as an integer is either even or odd.
A U B = {x : X is an even integer or an odd integer }
= { x : x is an integer }
A Π B = {x : x is an odd integer and an even integer }
= φ null set.
