distribution.

Definition of Terms

prob : hypergeometric cumulative probability (0  prob  1)
n :

number of trials from population (0  n integer)

M :

number of successes in population (0  M integer)

N :

population size (n

 N, M  N integer)

Calculation Result Output

xInv : inverse hypergeometric cumulative distribution
*xInv : recalculation value (Displayed only when there is the possibility of

rounding error.)

• To account for possible rounding error, ClassPad also obtains the result using

the probability that is next lowest for the least significant digit. For example, if
the probability is 0.3, ClassPad would recalculate using 0.29. The recalculation
result is only shown if it is different from the original one.

Graphing may take a long
time when the absolute value
of the argument is large.
