CLIMATE-ADAPT
The likelihood of an occurrence, an outcome or a result, where this can be estimated probabilistically. [1]
European Project Definitions
CIPRNet project
The CIPRNet project [2] uses the following definition:
Likelihood is the chance of something happening.
RESIN project
The RESIN project [3] gives the following definition:
The chance of a specific outcome occurring, where this might be estimated probabilistically. [4]
Other International Definitions
IPCC
Likelihood: A probabilistic estimate of the occurrence of a single event or of an outcome, for example, a climate parameter, observed trend, or projected change lying in a given range. Likelihood may be based on statistical or modeling analyses, elicitation of expert views, or other quantitative analyses. [5]
National Definitions
Canada
Likelihood: The chance of an event or incident happening, whether defined, measured or determined objectively or subjectively.
Vraisemblance: Possibilité qu’un événement ou un incident se produise, que celle-ci soit définie, mesurée ou déterminée de manière objective ou subjective. [6]
Vraisemblance: Possibilité qu’un événement ou un incident se produise, que celle-ci soit définie, mesurée ou déterminée de manière objective ou subjective. [6]
France
Vraisemblance: Estimation de la possibilité qu’un scénario de menace ou un risque, se produise. Elle représente sa force d’occurrence. [7]
Likelihood: Estimate of the possibility that a threat scenario or a risk will occur. It represents the estimated level of possibility. [8]
Likelihood: Estimate of the possibility that a threat scenario or a risk will occur. It represents the estimated level of possibility. [8]

Likelihood: A weighted factor based on an analysis of the probability that a given threat is capable of exploiting a given vulnerability. (NISTIR 7298r2 Glossary of Key Information Security Terms) [9]

(I risikoanalyser) brukes ofte sannsynlighet som mål på hvor trolig vi mener det er at en bestemt hendelse vil inntreffe, gitt vårt kunnskapsgrunnlag. [10]
(In risk analyses) likelihood is often used as an expression of how likely we think it is that a specific event will occur, given our knowledge base. [11]
