• . n_0(A) = n(A)-n(A cap B)-n(A cap C)+n(A cap B cap C)
  
  5. n_0(B) = n(B)-n(A cap B)-n(B cap C)+n(A cap B cap C)
  
  6. n_0(C) = n(C)-n(A cap C)-n(B cap C)+n(A cap B cap C)
  
  7. n(A cap B only) = n(A cap B)-n(A cap B cap C)
  
  8. n(B cap C only) = n(B cap C)-n(A cap B cap C)
  
  9. n(A cap C only) = n(A cap C)-n(A cap B cap C)
