Likelihood 10
Likelihood 10 : Estimate of the potential of an incident or event's occurrence. (DHS Risk Lexicon 9/08) Qualitative and semi-quantitative risk assessments can use qualitative estimates of likelihood such as high, medium, or low, which may be represented numerically but not mathematically. Quantitative assessments use mathematically derived values to represent likelihood. (DHS Risk Lexicon 9/08)
