Event-B Qualitative Probability User Guide
From Event-B
User:Son at ETH Zurich is in charge of the plug-in.
Introduction
Event-B Qualitative Probability plug-in provides supports for reasoning about termination with probability 1 (almost-certain termination).
Installing and Updating
The plug-in is available through the main Rodin Update Site under Modelling Extension category.
