geometric distribution

In probability theory and statistics, the geometric distribution is either one of two discrete probability distributions:
- The probability distribution of the number ${\\displaystyle X}$ of Bernoulli trials needed to get one success, supported on the set ${\\displaystyle \\{1,2,3,\\ldots \\}}$ ;
- The probability distribution of the number ${\\displaystyle Y=X-1}$ of failures before the first success, supported on the set ${\\displaystyle \\{0,1,2,\\ldots \\}}$ .
Which of these is called the geometric distribution is a matter of convention and convenience.
