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 xInv (calculation result using Area) and `xInv (calculation result using `Area). The calculator always displays the xInv value only. However, when the xInv and `xInv 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. 6-63
