About Risk Probability and Chance
Risk Probability is the calculated chance that an event will occur. You can view risk probability in the Risk Matrix, Risk Register, and other views and dialog boxes. Risk Chance is the input parameter for risk probability. Risk chance (input parameter) and risk probability (calculated attribute) can be different, particularly when a risk has multiple mutually exclusive alternatives as risk chance is an input parameter for each alternative. In these cases, Risk probability is calculated based on the risk chance for each mutually exclusive alternative.
