Experience Another method,known as the frequency method had also been used for some time. This method consists of repeating a game a large number of times under the same conditions.The probability of winning is then approximately equal to the proportion of wins in the repeats. This method was used by Pascal and Fermat to verify results obtained by the classical method. History of Probability 6History of Probability 6 Experience !
