    "abstract": "For a class of mixed two -qubit states we show that it is not possible to\ndiscriminate between states violating or non - violating Bell - CHSH\ninequalities, knowing only their entanglement and mixedness. For a large set of\npossible values of these quantities, we construct pairs of states with the same\nentanglement and mixedness such that one state is violating but the other is\nnon - violating Bell - CHSH inequality.",
