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 16.
