Logic Flow Chart App

[hh]

Of course the eight cases are

A and B and C
A and B and not C 
A and not B and C
not A and B and C
A and not B and not C
not A and B and not C
not A and not B and C
not A and not B and not C

You know: There are three kinds of mathematicians: A first kind is able
to count, the second one is not ;-)
