Note: To avoid confusion, definitions of the following terms as used for the purposes of this article are provided below.
Frequency: The rate at which a certain event occurs, expressed in terms of events per unit time (e.g., “explosions per year”), Probability: The odds or expectations that a certain event will occur, given a stated starting point (e.g., the probability that I roll a “3” on a single die is 1/6). The units of probability are dimensionless, Likelihood: A term that can be used in place of either “frequency” or “probability,” and generally both in the context of this paper.
