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.

poissonpdf(mean, outcome)

[2^{ND}] | [VARS] | [ENTER] | [.] | [3] | [2] | [5] | [,] | [3] | [ENTER]

### 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)

[2^{ND}] | [VARS] | [ALPHA] | [x^1] | [5] | [,] | [4] | [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)

[1] | [-] | [2^{ND}] | [VARS] | [ALPHA] | [x^1] | [5] | [,] | [5] | [ENTER]

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.
