Question

If A = { 1,3, 5, 9,11,13,15} and B = { 1, 9, 11, 15}. (i) Find A U B (ii) A∩ B
(iii) Represent the given set in Venn diagram.​

Answer 1

Answer:

i){1,3,5,9,11,13,15}

ii){1,9,11,15}

iii)can't represent with keyboard

Answer 2

Answer:-

Your Answers are as follows:-

• $\bf A\cup B = \{1, 3, 5, 9, 11, 13, 15\}.$

• $\bf A\cap B = \{1, 9, 11, 15\}.$

• (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).
