The Frequentist Intuition behind Assigning Probabilities
An event is something that might or might not occur when some repeatable procedure is performed. A frequentist approach to probability entails assigning a probability to an event such that the relative frequency with which occurs approaches as the number of repetitions of the procedure grows.[more]
In this Demonstration, the procedure is the tossing of three fair dice. You can choose from a few events and watch how the relative frequency of their occurrence (blue plot) fluctuates about the theoretical probability assigned to them (red line).[less]
