Introduction to Probability Theory The materials from “Artificial
... The probability could be thought as a measure of one’s belief in the occurrence of a future event. Some events cannot be predicted with certainty, but the relative frequency with which they occur in a long series of trials is quite stable. This relative frequency is commonly used as a measure of bel ...
