Exampler A computer program, which performs exactly according to a set of instructions. The probabilistic system can be described in terms of probable behavior, but a certain degree of error is always attached to the prediction of what the system will do. Examp| e:- A set of instructions given to a human who, for a variety of reasons, may not follow the instructions exactly as given.
