Hypergeometric Distribution Calculator in GeoGebra

Here’s how you can use the Probability Calculator GeoGebra icon in GeoGebra to compute probabilities from the hypergeometric distribution.

GeoGebra Instruction 1

1.
Open Probability Calculator GeoGebra icon under GeoGebra icon View in GeoGebra icon Menu.
2.
Make sure that you choose the Distribution tab at the top of the window.
3.
Select Hypergeometric from the drop-down list.

  • Population is the total population.

  • n the number of elements in group A.

  • Sample is the sample size, that is, the number of elements you draw.

4.
Choose Left-sided GeoGebra icon, Interval GeoGebra icon, Two tailed, or Right-sided GeoGebra icon depending on your problem.

  • If you’re asked to compute the probability of getting exactly k elements from A, you can find it in the table on the right-hand side.

  • If you’re asked to compute the probability of getting at least k elements from A, choose Right-sided GeoGebra icon and enter the value of k.

  • If you’re asked to compute the probability of getting at most k elements from A, choose Left-sided GeoGebra icon and enter the value of k.

  • If you’re asked to compute the probability that the number of elements drawn from A will be between N and M, including N and M, choose Interval GeoGebra icon and enter the values of N and M.

  • If you’re asked to compute the probability that the number of elements drawn from A is not between N and M, choose Two tailed and enter the values N 1 and M + 1. Alternatively, you can compute the probability in the item above, and then take it and subtract it from 1.
