For a random sample x1, x2,...of observations on a discrete random variable X, the likelihood (a term coined by Sir Ronald Fisher in 1921) is proportional to the product of the probabilities of the individual values:




.
When X is continuous, a reported value xj has to be regarded as meaning that the observed value is (in general) in the interval (xjδ, xj+δ), where δ represents the accuracy of measurement. The likelihood is then proportional to



.
If δ is very small then this is approximately proportional to



,
where f is the probability density function of X.




In mathematics, a subjective assessment of possibility that, when assigned a numerical value on a scale between impossibility (0) and absolute certainty (1), becomes a probability (see probability theory). Thus, the numerical assignment of a probability depends on the notion of likelihood. If, for example, an experiment (e.g., a die toss) can result in six equally likely possible outcomes, the probability of each is 1/6.
