Question

If P={1,3,6,7,9} and Q={1,2,4,5,6,7,8), find P n Q.{}{1, 2, 3, 4, 5, 6, 7, 8, 9}{1, 6, 7}{2, 3, 4, 5, 8, 9}

Answer 1

Given:

P={1,3,6,7,9}

Q={1,2,4,5,6,7,8)

We have to find P ∩ Q.

The symbol ∩ insdicates intersection. So, P ∩ Q indicates the intersection of P and Q.

The intersection of two sets P and Q is the set of all elements that are common in both P and Q.

The elements common in both P and Q are 1, 6, 7.

Therefore, P ∩ Q={1, 6,7}.
