 0 answersPost by Ken Mullin on January 24, 2012RE: the marble example What might aid a student here is seeing that this type computation yields the same answer as if the calculation was performed by simply doing the multiplication of each event (w/0 replacement)--> (5/10)*(4/9)*(3/8) = .08333..I wouldn't have thought to use the hypergeometric prob. distrib here. What would be the advantage in doing do, if any? 0 answersPost by Malinda Holland on November 9, 2010Is the answer in the Marbles example correct ? I think 0.083 should be 0.0083 (the probability reduces to 1/120 not 10/120)

### Geometric and Hypergeometric Probability Distributions

• The geometric distribution is used to find the probability that the first success occurs on the xth trial.

• For the geometric distribution, the trials are independent and have two outcomes: “success” or “failure.”

• The hypergeometric distribution is used when sampling without replacement.
