A language is called stochastic if and only if there is some 0 ≤ η < 1 {\displaystyle 0\leq \eta <1} for which L η {\displaystyle L_{\eta }} is η-stochastic.
یک زبان را تصادفی (stochastic) گوییم اگر و تنها اگر 0 ≤ η < 1 {\displaystyle 0\leq \eta <1} موجود باشد به طوری که L η {\displaystyle L_{\eta }} η-stochastic باشد.
