  • When conducting experiments, scientists assume equiprobability to ensure that all outcomes are equally likely to occur.

Examples

  • The standard statistical approach defines 'randomness' in terms of equiprobability: a selection of an n-fold set from a population is random just in case every n-fold set is as likely to have been drawn from that population as any other.

    Academic text (2001)

Morphology

equiprobability = probability (transparent) = equi + probability

Formed by prefixing equi- ('equal') to 'probability', so the meaning 'equal probability' is directly derivable.

Etymology

Equiprobability joins equi- meaning 'equal', like in equal, and probability meaning 'chance'. So, it means every possible outcome has the 'same chance' of happening.
