Producing random numbers with the geometric distribution: randgeometric

The randgeometric command finds random numbers chosen according to the geometric distribution (see Section 9.4.13).

randgeometric takes one argument:
p, a probability (a number between 0 and 1).
randgeometric(p) returns a number chosen randomly according to the geometric distribution with probability p.

Example.
Input:

randgeometric(0.2)

Output (for example):
