Answer 4

yes

Answer 5

Now work through each part one by one, finding each region. I gotta go out but I'll finish later.

Start by finding regions for A:
I, II, IV, V
Regions for ~C (ie every region outside C):
I, II, III, VIII


Now, (A U ~C) means A union ~C, so combine the regions for A and ~C (remove any doubles/overlaps).


Once you have that, find ~B (every region outside B)
then (A U ~C) n ~B means everything (A U ~C) has in common with ~B.
