??

Answer 9

AuB

Answer 10

Yes this operator that is in between A and B is called Union..

In Union of two sets A and B, we combine all the terms of A and B..

Can you tell me what can be the answer if we combine the elements of A and B..??

Answer 11

See, if an element is present in both the sets, then we write it once and is not repeated..

For example:

A = {1, 2, 3, 4}

B = {2, 5, 7}

Then,

AUB = {1, 2, 3, 4, 5, 7}

Here we can't write 2 two times in the AUB..
