| Abstract: | Five formulae of distribution recurrsion such as binomial, Poisson, hypergeometry, Pascal and hyper Pascal, have been obtained in the paper, Thus by these formulae the expectation and variance are calculated and the expectation is jnst the coefficient of the probability distribution at the right side of the recurrsion formula. |
