## probability

(ˌprɒbəˈbɪlɪtɪ)
n, pl -ties
1. the condition of being probable
2. an event or other thing that is probable
3. (Statistics) statistics a measure or estimate of the degree of confidence one may have in the occurrence of an event, measured on a scale from zero (impossibility) to one (certainty). It may be defined as the proportion of favourable outcomes to the total number of possibilities if these are indifferent (mathematical probability), or the proportion observed in a sample (empirical probability), or the limit of this as the sample size tends to infinity (relative frequency), or by more subjective criteria (subjective probability)
