"random distribution" is like "accidental distribution". "random 
variable" is much more frequently used definition is stats world 
(stats world != stats packages). Also this better describes what 
functionality provides module. "Distribution" may be used for PDF 
or for CDF (or their pair). "probability distribution" and 
"random variable" looks better (IMHO) then "random distribution", 
which has another meaning in stats world: a distribution, which 
was chosen randomly from a class of distributions. For example, 
variance-mean mixtures. --Ilya
