probability games of chance Gerolamo Cardano Pierre de Fermat Blaise Pascal problem of points Christiaan Huygens classical definition of probability Pierre Laplace event
The modern mathematical theory of probability has its roots in attempts to analyze games of chance by Gerolamo Cardano in the sixteenth century, and by Pierre de Fermat and Blaise Pascal in the seventeenth century (for example the "problem of points"). Christiaan Huygens published a book on the subject in 1657. In the 19th century, what is considered the classical definition of probability was completed by Pierre Laplace.
