Find A ∩ B if A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}.

Solution:

The intersection of sets A and B is A ∩ B. The elements are common in both sets.

A = {2, 5, 8, 11, 14}

B = {1, 3, 5, 7}

So we know that

A ∩ B means the elements which are present in both sets A and B.

A ∩ B = {5}

Therefore, A ∩ B = {5}.

Find A ∩ B if A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}.

Summary:

If A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7} then A ∩ B = {5}.
