Find A ∩ B

If A and B are sets, the intersection of A with B, denoted
A ∩ B, is the set consisting of elements that belong to both A and B.

Given set A = {w, x, y, z} and set B = {e, pi, x, y}

A ∩ B = {w, x, y, z} ∩ {e, pi, x, y}

A ∩ B = {x, y}

I think is correct.

Ok. I guess it was just pure luck at my end. The textbook begins with basic set theory. It is not a set theory book.
