A model according to which contact-angle hysteresis arises as the result of a random distribution of irregularities on the solid surface is investigated on the basis of probability theory. An estimate is obtained of the mathematical expectation of the number of stable equilibria when the effective a

## Abstract With the introduction of an additional interfacial tension (or hysteresis tension) to describe the effect of the surficial roughness on the liquidβsolid contact angle hysteresis, both contact angle and its hysteresis were derived from mechanical equilibrium and were perfectly consistent
