 Most legal probabilists agree that the probabilities ascribed to statements that are disputed in a trial—such as “The defendant is the source of the crime traces” or “The defendant was at the crime scene when the crime was committed”—should be understood as evidence-based degrees of belief (see, for example, Cullison 1969; Kaye 1979b; Nance  2016). This interpretation addresses the worry that since past events did or did not happen, their probabilities should be 1 or 0. Even if the objective chances are 1 or 0, statements about past events could still be assigned different degrees of belief given the evidence available. In addition, degrees of belief are better suited than frequencies for applications to unrepeatable events, such as actions of individuals, which are often the focus of trial disputes Further engagement with these issues lies beyond the scope of this entry (for a more extensive discussion, see the entry on the  interpretations of probability as well as Childers 2013; Gillies 2000; Mellor 2004; Skyrms 1966).
