Set Theory

Every field in the present world involves a set. The theory of sets was developed by German mathematician Georg Cantor while working on the “problems of trigonometric series”.

Question

Consider the following statement.

For all sets $ A $ and $ B $, $ (A \cup B)^c = A^c \cup B^c $.

Which sentence below expresses what it means for the statement to be false? (Select all that apply.)

- [ ] There are sets $ A $ and $ B $ such that $ (A \cup B)^c \neq A^c \cup B^c $.
- [ ] For all sets $ A $, there is a set $ B $ such that $ (A \cup B)^c \neq A^c \cup B^c $.
- [ ] There is a set $ A $ such that for all sets $ B $, $ (A \cup B)^c \neq A^c \cup B^c $.
- [ ] For all sets $ A $ and $ B $, $ (A \cup B)^c \neq A^c \cup B^c $.

Find subsets of $ \{1, 2, 3, 4, 5\} $ which can be used to show that the given statement is false. (Enter the sets as $ A, B $ in a comma-separated list. Use set-roster notation or write EMPTY or $ \emptyset $ for the empty set.)

$ A, B = $ [Input box]
