Question

Can someone please help me with these two

Answer 1

1a. {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

1b. {5}

Explanation:

For part 1:

A U B is the union of all values, so {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

Remember that union means to include all values.

A n B is the intersection of all values, so {5}

Remember that the intersection means "what do they have in common".
