Probability can be defined in at least five different ways:
1. Classical Laplacean theory of probability: The prob.is derived from
the fairness assumption e.g. a fair coin. It is also called
equiproability.
2. Frequentist theory: It is developed by von Mises and Reichenbach. Prob.
is the relative frequency in the long run by limiting observations.
3. Propensity: It is based upon the physical or the objective property of
the events.
4. Logical: developed by Carnap. Prob. is defined like Y logically
entails X.
5. Subjective or Bayesian: degree of belief
There is no easy answer to your question. It depends on which point of
view you chose.
