The complement of A in U = {1, 2, 3, 4, 5} where A = {2, 4} is:

• {2, 4}

• {1, 3, 5}

• {1, 2, 3, 4}

• {1, 2, 3, 4, 5}

The Cartesian product A × B where A = {1, 2}, B = {x, y} is:

• {(1, x), (2, y)}

• {(x, 1), (y, 2)}

• {(1, x), (1, y), (2, x), (2, y)}

• {(x, 1), (y, 1), (x, 2), (y, 2)}

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10},

A = {1, 3, 5, 7, 9},

B = {2, 3, 5, 7, 10}.

• {2, 10}

• {3, 5, 7}

• {1, 9}

• {4, 10}
