An appeal to probability (or appeal to possibility, also known as possibiliter ergo probabiliter, "possibly, therefore probably") is the logical fallacy of taking something for granted because it is possibly the case.
[1][2] The fact that an event is possible does not imply that the event is probable, nor that the event was realized.
A fallacious appeal to possibility: Murphy's law is a (typically deliberate, tongue-in-cheek) invocation of the fallacy.
