geometric random variable
probability of success
The geometric random variable is a discrete probability random variable with probability function given by:
subject to the following conditions:
The geometric random variable has the lack of memory property: the probability of an event occurring in the next time interval of an exponential random variable is independent of the amount of time that has already passed.
The geometric variate is a special case of the NegativeBinomial variate with number of trials parameter x=1.
The continuous analog of the geometric variate is the Exponential variate.
