Abstract
In this chapter we can find various numbers of EB members of the experiment “M sided N dice taken V at a time”. Beside this we can find various numbers of IB members of different IB experiment i.e., of the experiments M sided N dice taken V at a time in which first v dice are identified in the first way or second way or both way. Again various numbers of B events can be calculated from different CB experiments i.e., of the experiments M sided N dice taken V at a time in which first v dice are identified in the first way or second way or both way. Moreover we can find varies numbers of GB members of different GB experiment i.e., of the experiments M sided N dice taken V at a time in which X is observed in the first way or Y is observed in the second way or X, Y are observed in the both way at a time. X and Y are variables. Beside this we can get combination theorems, permutation theorems, formation theorems and homogenation theorems from these theorems.

1. Introduction
First of all I discussed Biswas theorem and then elementary B theorems. They are divided into four parts; both way selected B (SB) theorem, both way arranged B (AB) theorem, first way selected and second way arranged B (SAB) theorem and first way arranged and second way selected B (ASB) theorem.Then identified B theorems are divided into four parts i.e.,(i) both way selected B (SB) theorem(ii) both way arranged B (AB) theorem(iii) first way selected and second way arranged B (SAB) theorem(iv) first way arranged and second way selected B (ASB) theorem. Similarly characterizing B theorems and general B theorems are divided into the same.
