|A| = a+ab+ac+abc
|A|
|B| = b+ab+bc+abc
|B|
|C| = c+ac+bc+abc
|C|
|A∩B| = ab+abc
|A∩B|
|A∩C| = ac+abc
|A∩C|
|B∩C| = bc+abc

Key EGE No. 6 formulas:
Inclusion formula (2 multiples):
|A∪B| = |A| + |B| − |A∩B|
Inclusion formula (3 sets):
|A∪B∪C| = |A|+|B|+|C| − |A∩B| − |A∩C| − |B∩C| + |A∩B∩C|
Only A (without B and C):
a = |A| − |A∩B| − |A∩C| + |A∩B∩C|
A ± B without C:
ab = |A∩B| − |A∩B∩C|
