a single experiment in which the only two possible outcomes are success or failure. Usually a value of 0 is used to denote a failure (i.e., the item of interest does not occur) and a value of 1 is used to denote a success (i.e., the item does occur). A sequence of Bernoulli trials is known as a Bernoulli process. See also Bernoulli distribution. [Jacques Bernoulli]
