Abstract.

Given a variety \( \cal V \) of algebras, what is the probability that for an arbitrary identity p \( \approx \) q the only algebra in \( \cal V \) that satisfies p \( \approx \) q is the trivial algebra? More generally, if \( \cal W \) is a subvariety of \( \cal V \) what is the probability that p \( \approx \) q together with the identities of \( \cal V \) forms an equational basis for \( \cal W \)? We consider these questions for various \( \cal V \) and \( \cal W \) and we provide criteria that allow for explicit determination of these probabilities.

Key words and phrases: Variety, identity, probability, Fraser-Horn Property.
