This is to announce a new version of an electronic preprint concerning an application of meadows. The preprint “Signed Meadow Valued Probability Functions” has now been replaced by a substantial revision with the new title “Probability functions in the context of signed involutive meadows” (arXiv:1307.5173v3 [math.LO]). An equation that was mentioned as an axiom before is in fact derivable from the other axioms. This fact called for a significant change in emphasis and presentation. In addition a survey has been

provided of some options to turn conditional probability into a total operator.
