Distribution
# There is no graphing for geometric
distribution.
# Positive integer number is calculated whether
list data (Data:List) or x value (Data:variable)
is specifi ed.
k Geometric Distribution
u Geometric Probability
Geometric probability calculates the probability at a specifi ed value, and the number of
the trial on which the fi rst success occurs, for the geometric distribution with a specifi ed
probability of success.
(
x = 1, 2, 3, ···)
Perform the following key operations from the statistical data list.
5(DIST)
6(g)2(GEO)
1(Gpd)
The following shows the meaning of each item when data is specifi ed using list specifi cation.
Data ............................ data type
List .............................. list whose contents you want to use as specifi ed 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 specifi cation item that is different from
list data specifi cation.
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.
Calculation Result Output Example
p ................................. geometric probability
(x) = p(1– p)
x – 1
(x) = p(1– p)
x – 1
