1a. {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}
1b. {5}
Step-by-step 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".
