Answer
Probabilistic Context-Free Grammar (PCFG)
Work Step by Step
One example of a non-deterministic language is **Probabilistic Context-Free Grammar (PCFG)**. In PCFG, the production rules have associated probabilities, indicating the likelihood of each rule being chosen during the parsing process. This means that for a given input string, there may be multiple possible parse trees, and the choice between them is influenced by the probabilities assigned to the production rules. Thus, the language generated by a PCFG is non-deterministic, as it allows for multiple valid interpretations of the same input.
