This is an activity to explore the Negaive 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 negative binomial with \( r=5, \ p=0.2 \).
- b. \( X \) follows negative binomial with \( r=5, \ p=0.9 \).
- c. \( X \) follows negative binomial with \( r=20, \ p=0.3 \).
- d. \( X \) follows negative binomial with \( r=20, \ p=0.9 \).
- Exercise 2: Let \( X <\math> follows the negative binomial distribution with <math> r=5, \ p=0.2 <\math>. Explain in words what <math> P(X > 10) \) means and use SOCR to compute this probability.
Below you can see the distribution of \( X \sim b(20,0.3) \)
