Question

find the union and intersection of the following pair of sets...

Answer 1

A={2, 3, 5, 6, 7}

B={4, 5, 7, 8}

Now

A U B=UNION OF A AND B., which means a single set having all the elements of set A and B

therefore.,

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

NOW.,

A Π B represents intersection of A and B... which means a set containing common elements in set A and B

here we have 5 and 7 common in both
hence

AΠB ={5, 7}

Answer 2

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

Then

A union B

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

And

A intersection B

{5,7}
