Maths Help

hey,
currently doing a discreet maths course and got on to the topic of set theory, I was wondering if someone could tell me weather I have the right answer to this questions I have answered.

Considering any 4 subsets of a universe, U, work out (and show your
working)
(1) how many different regions there could be.

My answer was 8 different regions.

(vi) how many different ways of combining these regions using boolean com-
binations are there?

I got this to 256 combining these regions.

I know this may be plain english to some people,But it has been so long since I touch on mathmatics

Thnaks in advance

Jason
