A French gambler, Chevalier de Metre asked Pascal to explain
some seeming contradiction between his theoretical reasoning and the
observation gathered from gambling In a series of letters written around 1654,
Pascal and Fermat laid the first foundation of science of probability Pascal solved
the problem in algebraic manner while Fermat used the method of combinations Great Dutch Scientist, Huygens (1629-1695), became acquainted with the
content of the correspondence between Pascal and Fermat and published a first
book on probability, "De Ratiociniis in Ludo Aleae" containing solution of many
interesting rather than difficult problems on probability in games of chances
