What does it mean to suppose that something is the case based on probability?

To presume something based on probability means to accept it as true or likely true based on available evidence or reasoning. In the context of probability, this implies an assumption that has a reasonable basis in the evidence at hand, even though it may not be definitively proven.

Presumption involves a level of confidence tied to the likelihood of an event or situation occurring. For instance, one might presume that an individual is guilty until proven innocent, based on the evidence presented. This is different from mere conjecture or speculation, which involve more uncertainty or hypothetical thinking without the same weight of evidence or support. By choosing to use the term 'presume,' one aligns with a standard that acknowledges both probability and some grounding in fact, distinguishing it from less substantiated claims.
