We address the problem of extending probability from the total choices of an ASP program to the standard models, and from there to general events.
%
Our approach is algebraic in the sense that it relies on an equivalence relation over the set of events and uncertainty is expressed with variables and polynomial expressions.
%
We illustrate our methods with two examples, one of which shows a connection to bayesian networks.

Possible applications of the process described here include assigning a score to a logic program with respect to the empiric distribution of a given dataset, which in turn can be used by evolutionary algorithms searching for optimal models of that dataset.
