Let ~II be r! times the r-content of an rsimplex whose P vertices are in the interior and r -I- /- p vertices on the boundary of a unit n-ball. Explicit expressions for the exact distribution functions of ~II are given when r I / points are independently, and identically distributed according to the Uniform distribution. The exact distributions are obtained using the technique of Inverse Mellin transforms with the help of the moment functions. The technique is illustrated for the general case p =- r -j J and a particular case p =3, r - 2 . Various representations of the distributions in psi and the generalized zeta functions are given. These representations are also given in the most general case as an H- function distribution. en_US SYMBOLS AND NOTATIONS The following is a list of symbols and notations, with meanings indicated on the right that will frequently occur in this Research.
