The sample space of an experiment is the set of all possible outcomes of that experiment. An event need not be a subset of the sample space. Estimated probability is not relative frequency. Estimated probability is an approximation of empirical probablity.
Empirical probability is an approximation of abstract probability.
Estimated probability and empirical probability are both examples of abstract probability. There are some events whose probability exceeds 1. 11. There is a one in six chance of rolling a pair of 7s if two dice are rolled. There is a one in six chance of rolling a pair if two dice are rolled. If two events are mutually exclusive, then the sum of their probabilities is 1. 14.
