Answer:-
Your Answers are as follows:-
\bf A\cup B = \{1, 3, 5, 9, 11, 13, 15\}.A∪B={1,3,5,9,11,13,15}.
\bf A\cap B = \{1, 9, 11, 15\}.A∩B={1,9,11,15}.
(See The Attachment).
More to know from above question:-
Here \cup∪ stands for union of the sets A and B i.e. all the elements in the sets A and B without repeating any element.
You may have also observed that union of A and B is set A, as all the elements in B is present in A so we can say that in above condition A is a subset of B (Represent by \bf\subset⊂ Symbol).
