Based on mixedness definition as $$M=1-\hbox {tr}\left( {\rho ^{2}}\right) $$M=1-trρ2, we obtain a new variance-based uncertainty equality along with an inequality for Hermitian operators of a single-qubit system. The obtained uncertainty equality can be used as a measure of the system mixedness. A qubit system with feedback control is also exploited to demonstrate the new uncertainty.
