Geometric probability
Geometric probability calculates a probability at specified value, the number of the
trial on which the first success occurs, for the discrete geometric distribution with
the specified probability of success.

The following shows the meaning of each item when data is specified using list
specification.
Data ................ data type
List .................. list whose contents you want to use as sample data
p
..................... success probability (0

The following shows the meaning of a parameter data specification item that is
different from list data specification.
x
..................... value
• Positive integer number is calculated whether list data (Data:List) or
x
value
(Data:variable) is specified.
Example To calculate geometric probability for one list of data
For this example, we will calculate geometric probability for data
= {3, 4, 5} when
p
= 0.4.
