Из условия видно, что:
X1 = M1 OR M2
Х2 = F2 OR F3
ХЗ = Н1 OR H3
Х4 = NOT (M1 AND M2) AND NOT (F2 AND F3) AND NOT (H1 AND H2)
Дополнительные условия, чтобы не было совпадения предметов на одну пару:
Х5 = NOT(M1 AND M2) AND NOT(M1 AND H1) AND NOT(F3 AND Н3) AND NOT(M2 AND F2)
Объединяя, получим уравнение:
X = X1 AND X2 AND X3 AND X5
