If X = {2, 4, 6, 8} and Y = {1, 2, 3, 6} then X ∩ Y = _____?

{2, 6}

{1, 2, 3, 4, 5, 6, 7, 8}

{2, 4, 6, 8}

None of these

The intersection of two sets X and Y (X ∩ Y) is the set of elements that are common to both X and Y.

Given:

X = {2, 4, 6, 8}

Y = {1, 2, 3, 6}

The common elements are 2 and 6.

So, X ∩ Y = {2, 6}.
