Find the following:

LIST the elements in the set (
A
∪
B
A
∪
B
):
(
A
∪
B
)
(
A
∪
B
)
= { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

LIST the elements in the set (
A
∩
B
A
∩
B
):
(
A
∩

)
(
A
∩
B
)
= { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
