Poisson Distribution; Poisson Probability - Casio FX-CG20 AU User Manual

Important!
When executing the Inverse Binomial 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.
Inv (calculation result using Area) and `
x x
The results are assigned to system variables Inv
(calculation result using `Area). The calculator always displays the
x
Inv value only. However,
x Inv and ` x
when the Inv values are different, the message shown below will appear with both
values.
The calculation results of Inverse Binomial 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.
