If A = {2, 3, 4, 5} and B = {5, 6, 7, 8}, what is A U B?
{2, 3, 4, 5, 6, 7, 8)
{5}

Hey

Here's your answer:

Solution:

A={2,3,4,5}

B={5,6,7,8}

A U B={2,3,4,5} U {5,6,7,8}

={2,3,4,5,6,7,8}

In case of Union,we have to list all the elements which are present in both sets.

Hope it helps...

Good luck on your assignment
