The calculation results of invGeoCDf are integers. Accuracy may be reduced when the
first argument 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.
Example: To determine the minimum number of trials when
prob
= 0.875,
pos
= 0.5

S hypergeoPDf
Function: Returns the probability in a hypergeometric distribution that the success will
occur on a specified trial.
Syntax: hypergeoPDf(
x
,
n
,
M
,
N
[ ) ]
Example: Determine the hypergeometric probability when
x
= 1,
n
= 5,
M
= 10,
N
= 20.

For more information, see “Hypergeometric Distribution Probability” on page 7-11-23.
S hypergeoCDf
Function: Returns the cumulative probability in a hypergeometric distribution that the
success will occur between specified lower value and upper value.
Syntax: hypergeoCDf(lower value, upper value,
n
,
M
,
N
[ ) ]
Example: Determine the hypergeometric cumulative distribution when lower value = 0,
upper value = 1,
n
= 5,
M
= 10,
N
= 20.
Menu Item: [Action][Distribution][hypergeoCDf]
For more information, see “Hypergeometric Cumulative Distribution” on page 7-11-24.
S invHypergeoCDf
Function: Returns the minimum number of trials of a hypergeometric cumulative
distribution for specified values.
Syntax: invHypergeoCDf(
prob
,
n
,
M
,
N
[ ) ]
Important!
When executing the invHypergeoCDf function the calculator uses the specified
prob
value and the value that is one less the
prob
value minimum number of significant digits
(*
prob
value) to calculate minimum number of trials values. The results are assigned to
the system variables
xInv
(calculation result using
prob
) and *
xInv
(calculation result
using *
prob
). The invHypergeoCDf function always returns the
xInv
value only. However,
when the
xInv
and *
xInv
values are different, the warning message shown below appears
showing both values.
