u u u u u Geometric probability
Geometric probability calculates whether data taken from a geometric distribution
is less than a specific value.
x – 1
f (x) = p(1– p)

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 <
Execute .......... executes a calculation
The following shows the meaning of parameter data specification item that is
different from list data specification.
x
..................... value
• Positive integer number is calculated whether list data (Data:List) or
(Data:variable) is specified.
