The minimum number of NOT gates in a Boolean circuit computing a Boolean function $f$ is called the inversion complexity of $f \cdot$ . In 1958, Markov determined the inversion complexity of every Boolean function and particularly proved that $ \lceil\log_{2}(n+1)\rceil$ NOT gates are sufficient to compute any Boolean function on $n$ variables. In this note, we consider circuits computing probabilistically, and prove that the decrease of the inversion complexity is at most a constant if probabilistic circuits compute a correct value with probability $1/2+p$ for some constant $p >0$ .
