Galileo analysed that when three dice are
thrown, the sum of the number that appear is more likely to be 10 than the sum 9,

cases for the appearance of number 9 Apart from these early contributions, it is generally acknowledged that the
true origin of the science of probability lies in the correspondence between two
great men of the seventeenth century, Pascal (1623-1662) and Pierre de Fermat
(1601-1665) 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
