Important!
When executing the Inverse Geometric Cumulative Distribution calculation, the calculator uses
the specified Area value and the value that is one less than the Area value minimum number
of significant digits ( `Area value) to calculate minimum number of trials values.
The results are assigned to system variables x Inv (calculation result using Area) and ` x Inv
(calculation result using `Area). The calculator always displays the x Inv value only. However,
when the x Inv and ` x Inv values are different, the message will appear with both values.
The calculation results of Inverse Geometric Cumulative Distribution are integers. Accuracy
may be reduced when the Area value has 10 or more digits. Note that even a slight difference
in calculation accuracy affects calculation results. If a warning message appears, check the
displayed values.
k Hypergeometric Distribution
• Hypergeometric Probability 5(DIST) 6( g
)
3(HYPRGEO) 1(Hpd)
Hypergeometric Probability calculates the probability at
a specific single
x -value or each list element, and the
number of the trial on which the first success occurs, for the
hypergeometric distribution with a specified probability of
success.
Calculation Result Output Examples
When a list is specified When variable ( x ) is specified
• There is no graphing for Hypergeometric Probability.
• Hypergeometric Cumulative Distribution
5(DIST) 6( g
)
3(HYPRGEO) 2(Hcd)
Hypergeometric Cumulative Distribution determines the
sum of probabilities (cumulative probability) that
x , in the
Hypergeometric Probability p ( x ), will fall within a range
specified from a Lower value to an Upper value.
