Poisson Distribution TI-84 | TI-83 Example

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.
Poisson Distribution Calculate the Mean first .325
poissonpdf(mean, outcome)

[2ND] | [VARS] | [ENTER] | [.] | [3] | [2] | [5] | [,] | [3] | [ENTER]
Poisson Distribution TI-84 and TI-83 image.  poissonpdf(.325,3 = .0041338349

 

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] | [5] | [,] | [4] | [ENTER]
The Poisson Distribution use poissoncdf function (5,4 .= 44049

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)

[1] | [-] | [2ND] | [VARS] | [ALPHA] | [x^1] | [5] | [,] | [5] | [ENTER]
1-poissoncdf (5,5) = .384 in TI-84 calculator

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.
