Question

Prove the following statement. Assume that all sets are subsets of a universal set U.

For all sets A and B, if

A^c ⊆ B

then

A ∪ B = U.

Hint: Once you have assumed that A and B are any sets with

A^c ⊆ B,

which of the following must you show to be true in order to deduce the set equality in the conclusion of the given statement? (Select all that apply.)

Prove the following statement. Assume that all sets are subsets of a universal set $ U $.

For all sets $ A $ and $ B $, if $ A^c \subseteq B $ then $ A \cup B = U $.

Hint: Once you have assumed that $ A $ and $ B $ are any sets with $ A^c \subseteq B $, which of the following must you show to be true in order to deduce the set equality in the conclusion of the given statement? (Select all that apply.)

- [x] $ A \cap B \subseteq U $
- [ ] $ U \subseteq A \cap B $
- [x] $ A \cup B \subseteq U $
- [ ] $ U \subseteq A \cup B $
