Distribution (DIST)
kGeometric Distribution
uGeometric 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, ···) |

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 20) |
p .................................. | success probability (0 < p <1) |
Save Res ..................... | list for storage of calculation results (None or List 1 to 20) |
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, align the cursor with [Execute] and then press the function key shown below to perform the calculation.
