What is the difference between Empirical Probability, Theoretical (Classical) Probability, and Subjective Probability?
Empirical probability is the ratio of the number of successful trials divided by the total
number of trials. Theoretical probability is the number of successful possible outcomes
divided by the number of total possible outcomes (assuming each outcome is equally likely),
Subjective probability is a professional’s estimate of the chance of an outcome occurring.
The law of large numbers suggests that as more

and more trials of a probability experiment are attempted the closer the more likely the
empirical probability will match the theoretical probability.
