Résumé : Let X = {x1, x2, ..., xn} be a finite set and Ω be an algebra of subsets of X called events. Let ≳ be a qualitative probability relation on Ω × Ω. A probability measure p is said to uniquely agree with ≳ if, for all A and B in Ω, A ≳ B if and only if p(A) ≥ p(B), and p is the only probability measure with that property. We give a sufficient condition for the existence of a uniquely agreeing probability measure which is significantly simpler and more general than Luce's (1967, Annals of Mathematical Statistics, 38, 780-786) condition. © 1989.
