1 American Journal of Mathematics and Statistics 2018, 8(4): DOI: /j.ajms Biswas Distribution Deapon Biswas Transport Officer, Private Concern, Chittagong, Bangladesh Abstract Here we get all the theoretical discrete distributions to the random experiment M sided N dice taken V at a time. It states joint probability functions as well as marginal probability functions of which number of possible outcomes is EB numbers and number of favorable outcomes is GB numbers. In this paper I introduce 20 definitions where first is the Biswas distribution and others are the related distributions that state different joint probability functions and marginal probability functions. Keywords Biswas distribution, SB distribution, AB distribution, SAB distribution, ASB distribution, First way B distribution, Second way B distribution, Both way B distribution, First way SB distribution, Second way SB distribution, Both way SB distribution, First way AB distribution, Second way AB distribution, Both way AB distribution, First way SAB distribution, Second way SAB distribution, Both way SAB distribution, First way ASB distribution, Second way ASB distribution, Both way ASB distribution 1. Introduction First of all Biswas distributions are divided into four parts i.e., (i) both way selected B distribution (SB distribution) (ii) both way arranged B distribution (AB distribution) (iii) first way selected and second way arranged B distribution (SAB distribution) (iv) first way arranged and second way selected B distribution (ASB distribution) And then each part divided into three parts again i.e., for B distribution we get (i) first way B distribution (ii) second way B distribution (iii) both way B distribution. 2.

(.1) The four independent finite constants M, N, U and V are known as the parameters of this distribution. Biswas distribution is a joint probability distribution and a theoretical discrete distribution. Here takes only non-negative values under the interval min(m, U) M +1 min(m, U, V) and takes only non-negative values under the interval min(n, U) N+V min(n, U, V). Any two dimensional random variable which follows B distribution is known as B-variate and denoted by the symbol (, ) B(M, N, U, V). b(, ; M, N, U, V) GBM N U EB M V N EB M N GB M V V (.2) Example.1: For the GB experiment GB 5 6 find P( 2, ) where the experiment is first way arranged and second way selected.
