You want to calculate the probability (Poisson Probability) of a given number of occurrences of an event (e.g. customers entering the shop, defectives in a box of parts or in a fabric roll, cars arriving at a tollgate, calls arriving at the switchboard) over a continuum (e.g. a specific time interval, length, volume, area or number of similar items). Just enter the requested parameters and you'll have an immediate answer.

- Enter the mean in the text field next to "Mean (average rate of occurrence)". The mean should be a natural number higher than 0.
- Enter the random variable in the text field next to "Variable (number of occurrences)". The variable is = 0, 1, 2 ...
- To correct an entry, click the Reset button.

Please walk through some Poisson Probability **examples**.
