2. Relevant equations

none.

3. The attempt at a solution

I tried to do the questions but im just not sure if i did it right. id appreciate if you can check my work and let me know what changes i have to make. thanks

the symbol "n" means "intersect"

U for Union

Suppose A n B = U and suppose that A is a proper subset of U then

x is an element of B but

x is not an element of A n B since x is not an element of A
