Question

If A={4,5,6} and B={3,5,7} {AnB}
​

Answer 1

Answer:A={1,2,3,5}

B={3,4,5,6}

A n B : A Intersection B

When we take intersection of two sets, we only take the elements which are common in both sets.

AnB = {3, 5}

Answer 2

The correct answer is 5.

Given: Sets = A={4,5,6} and B={3,5,7}.

To Find: Elements in {A ∩ B}.

Solution:

{A ∩ B} is intersection of A and B.

It means elements common in set A and set B.

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

As we can see A and B have only one element in common that is 5.

So {A ∩ B} = {5}

Hence,  {A ∩ B} = 5.
