Empirical probability uses the number of occurrences of an outcome within a sample set as a basis for determining the probability of that outcome.

Bayes' theorem is a formula for calculating the probability of an event. Learn how to calculate Bayes' theorem and see examples.

For example, the conditional probability of surviving to 4 years given survival to 1 year was calculated by dividing the 4-year survival rate by the 1-year survival rate.
