== Description ==

The distribution describes the number of independent trials taken to achieve one success.

''Prob(X=x) = p(1-p)^x+1^''

It follows that the tail probability is equal to:

''Prob(X>x) = (1-p)^x^''

The distribution is memoryless. That is to say, for any ''0 < s < t'',

''Prob(X>t|X>s) = Prob(X>t-s)''
