 So we are dealing with possible events, among which only one is actual. The fact that the actual event is not singled out by modal interpretations, as a point of principle, is what makes them fundamentally probabilistic. This aspect distinguishes modal interpretations from many-worlds interpretations, where all events are actual and in which probability must consequently be a problematic notion. Nevertheless, this modal unanimity about the fundamental role of probability does not mean that all modal interpretations agree about the interpretation of probability.
