Let `U` be the universal set, where:
`U = { 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 }`
Let sets `A`, `B`, and `C` be subsets of `U`, where:

`A = \{1,2,4,6,10\}`

`B = \{1,2,3,5,9,10,16\}`

`C = \{1,2,5,6,10,11\}`

Find the following:

LIST the elements in the set `A^c \cup \emptyset` :
`A^c \cup \emptyset` = { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

LIST the elements in the set `B \cap C` :
`B \cap C` = { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

LIST the elements in the set `B^c \cup C` :
`B^c \cup C` = { }
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 \cap C) \cap B^c` :
`(A \cap C) \cap B^c` = { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
