Upgrading from:

Statistics`DiscreteDistributions`

Distributions defined in this package have been added to the built-in Mathematica kernel.
The input syntax for DiscreteUniformDistribution has changed.
Random and RandomArray are replaced by RandomInteger.

Discrete distributions are now part of the built‐in Mathematica kernel:

Version 5.2

DiscreteUniformDistribution is now parameterized by a pair of integer endpoints {min,max}:

Version 5.2

DiscreteUniformDistribution allows for integer ranges for which min is not 1:

Random elements for discrete distributions are generated via RandomInteger:
