SOCR EduMaterials Activities NegativeBinomial Distributions

From Socr

This is an activity to explore the Negative Binomial Probability Distribution.

• Description: You can access the applets for the above distributions at http://www.socr.ucla.edu/htmls/SOCR_Distributions.html .

• Exercise 1: Use SOCR to graph and print the following distributions and comment on the shape of each one of them:
  • a. X follows the negative binomial distribution with .
  • b. X follows the negative binomial distribution with .
  • c. X follows the negative binomial distribution with .
  • d. X follows the negative binomial distribution with .

• Exercise 2: Let X follows the negative binomial distribution with . Explain in words what P(X > 10) means and use SOCR to compute this probability.

Below you can see the distribution of negative binomial with . In this graph you can also see the probability that the 5th success occurs on the 18th or 19th or 20th or 21st or 22nd trial.
