Chance: The constellation of undefined causal factors which are considered to be irrelevant to the causal relationship under investigation; often spoken of as if it were a single, independent agency; the expression “pure chance” is sometimes used to describe a state characterized by complete unpredictability, that is, an absence of any cause-effect relationships. The term “chance” is frequently a short-hand expression for “mean chance expectation” as in “deviation from chance.”
