Abstract:A discrete probability distribution named as distribution of exponential difference is presented in this paper,formula to calculate the most probable success number,mathematical expectation and Variance are derived for this distribution,relationship between this distribution and geometric distribution is discussed,a application of this distribution in Markovian chain is given.
Keywords:distribution of exponential difference  mathematical expectation  variance  geometric distribution  markovian chain
