Question

If A= {1,2,4,5,7,9} and B= {2,3,4} and U = {1,2,3,4,4,6,7,8,9} find a union b

Answer 1

Given:

A = {1,24,5,7,9}

and

B = {2,3,4}

To find A union B, that is, A U B, you have to find the set that contains all elements of A and B.

You can write the numbers in ascending order and do not repeat the numbers that are in

So,

A U B = {1,2,3,4,5,7,9}.

Answer: A U B = {1,2,3,4,5,7,9}.
