Discrete Random Variables
While Pascal and Fermat were the founders of probability theory, it was only known to the relatively small group of mathematicians and scientists who were part of their correspondence network. Huygens introduced the subject to the scientific public. Huygens is often cited by historians as being associated with what has been called the “Scientific Revolution.” He certainly was not the only one who was responsible for this historical event. However, in one respect he was both unique and pivotal. His book established a new way of looking at and answering questions about nature, in which uncertainty is represented in an explicit and quantifiable manner.
