[email protected] Clear-Sighted Statistics: An OER Textbook Module 7: Basic Concepts of Probability “It is remarkable that a science [probability] that began by considering games of chance should itself be raised to the ranks of the most important subject of human knowledge.”1 –Pierre-Simon Laplace “The most important questions in life are, for the most part, really only problems of probability.”2 –Pierre-Simon Laplace Two seventeenth century French mathematicians, Blaise Pascal and Pierre de Fermat have been considered the founders of probability theory for over 300 years. Between July and October of 1654, Pascal and Fermat exchanged a series of letters about dice games that addressed questions raised by Antoine Gombaud, who was also known as the Chevalier de Méré. Gombaud is often depicted as the gambler in this story.3 With their letters, Pascal and Fermat established the core components of modern probability theory. While only seven of these letters have survived, some of the leading mathematicians of the time were aware of and commented on this correspondence. One was the era’s top scientist, Christiaan Huygens and teacher of the mathematician Gottfried Wilhelm Leibniz, alluded to these letters in 1657.
