Joestat wants to help you do the following Poison Distribution problems using your TI-84 or TI-83 calculator.
Example 1: Poisonpdf problem
Tistats.com has on 65 images over 200 pages. What is the probability that the first page visited on tistats.com has 3 images.
First calculate the mean.
Example 2: Poisoncdf problem
If you worked customer service at Bed Bathroom and the Future and they receive an average of 5 complaints per hour.
P(average outcome over time, predicted outcome)
Problem 1: Poisson Distribution (Using TI-83 or TI-84)
What is the probability that during your first hour of work that your handle at most 4 complaints?
At most 4 is the same as 0, 1, 2, 3, or 4 complaints.
P(0;5) + P(1;5) + P(2;5) + P(3;5) + P(4;5) |
Probability (4 or less)
poissoncdf (average outcome over time, predicted outcome)
[2ND] | [VARS] | [ALPHA] | [x^1] |  | [,] |  | [ENTER]
Problem 2: Poisson Distribution (Using TI-83 or TI-84)
What is the probability that during the first hour of working you handle 6 or more complaints?
1-poissoncdf (average outcome over time, predicted outcome)
1- (Probability of 5 or less)
Congratulations, you have learned how to complete multiple Poisson Distribution problems with your TI-83 and TI-84 calculator using the poissonpdf and poissoncdf functions.
