It has replaced much of the hours of hand work, pencil to paper calculations, and long hours. Numerical computations, in the computer technology world have been greatly upgraded and more valuable".The fundamental principle of probability is counting. In other words one thing can be accomplished in different ways. An example would be if you were required to seat 5 men and 4 women in a row so that the women occupy the even places. How many such arrangements are possible?The basic formula would be the men are seated in 5P5 ways and the women in 4P4 ways. If you were to calculate it all out the end would result that from a mathematical stand point there would be 2880 arrangement possibilities. From there other variables can play a role that could also impact the probability of what would or would not work.The beginning of probability:A gambler's dispute in 1654 led to the creation of a mathematical theory of probability by two famous French mathematicians, Blaise Pascal and Pierre de Fermat.
