You can put this solution on YOUR website! It depends on how many of the other two sets overlap the region indicating Set A. If A is all by itself, then the answer is 1. If A overlaps just one of B or C, then the answer is 2. And so on... There are a couple of different situations that could give you an answer of 3 regions, and one situation where you could get an answer of 4 regions -- which I suspect is what you were trying to describe.
If it is 4 regions:
1 represents elements that are a member of Set A only.
1 represents elements that are a member of both A and B but not C.
1 represents elements that are a member of both A and C but not B.
and the last 1 represents elements that are a member of all three sets.
