u u u u u Geometric Probability
Geometric probability calculates the probability at a specified value, and the number of the
trial on which the first success occurs, for the geometric distribution with a specified
probability of success.
f (x) = p(1– p) x – 1 ( x = 1, 2, 3, ···)
Perform the following key operations from the statistical data list.

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 specified data
(List 1 to 26)
p .................................. success probability (0 < p < 1)
Save Res .................... list for storage of calculation results (None or List 1 to 26)
Execute ....................... executes a calculation
The following shows the meaning of a parameter data specification item that is different from
list data specification.
x .................................. positive integer ( x > 1)
After setting all the parameters, use c to move the highlighting to “Execute” and then press
the function key shown below to perform the calculation.
•1(CALC) ... Performs the calculation.

Distribution
# There is no graphing for geometric distribu-
tion.
# Positive integer number is calculated whether
list data (Data:List) or x value (Data:variable)
is specified.
