The solution of the problem of intersection with a level is used as the basis for the probabilistic approach to describing the microtopography of a real surface on the assumption that the number of its projections is equal to the number of its pits. In this way one determines the number of nucleation sites. Starting with determination of the stable size of the vapor-phase nucleus generated in pits of rough surfaces, numerical solutions are obtained for the number of nucleation sites. This number provides to be in satisfactory agreement with the experimental data on the boiling of water on various surfaces.
