This Is a Certified Answer

Certified answers contain reliable, trustworthy information vouched for by a hand-picked team of experts. Brainly has millions of high quality answers, all of them carefully moderated by our most trusted community members, but certified answers are the finest of the finest.
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.
