Abstract
It is shown that different power indices defined in simple games can be obtained under a similar probabilistic approach: 1) establishing a bargaining model and 2) deciding which kind of winning coalitions are assumed to be formed. The power indices defined with this model include, among others, the well-known Banzhaf, Johnston or Deegan-Packel indices
