Here’s how you can use the Probability Calculator
in GeoGebra
to compute probabilities from the hypergeometric distribution.
GeoGebra
Instruction 1
Probability Calculator
under View
in Menu
. Distribution
tab at the top of the window. Hypergeometric
from the drop-down list. Population
is the total population.
the number of elements in group .
Sample
is the sample size, that is, the number of elements you draw.
Left-sided
, Interval
, Two tailed
, or Right-sided
depending on your problem. If you’re asked to compute the probability of getting exactly elements from , you can find it in the table on the right-hand side.
If you’re asked to compute the probability of getting at least elements from , choose Right-sided
and enter the value of .
If you’re asked to compute the probability of getting at most elements from , choose Left-sided
and enter the value of .
If you’re asked to compute the probability that the number of elements drawn from will be between and , including and , choose Interval
and enter the values of and .
If you’re asked to compute the probability that the number of elements drawn from is not between and , choose Two tailed
and enter the values and . Alternatively, you can compute the probability in the item above, and then take it and subtract it from 1.
