6 Extra Practice Answers Chapter Review. An experimental probability is calculated using the experimental results. Theoretical probability is found by dividing the number of favourable outcomes by the total number of outcomes. Subjective judgment is usually made by one s personal experience or feeling. For example, if five s are obtained by rolling a number cube 0. a) times, is an experimental probability, but 0 since there is only one on a number cube, the theoretical probability of getting a is. Also, because s are obtained frequently, one can make a subjective judgment that the next roll will produce another.
