This app lets you study different probability distributions such as Binomial, Normal or Exponential. Input the distribution’s parameters and get the corresponding probabilities. It is organized in 3 steps:
Once you have made a choice and moved to the next step, you can return to the previous step by pressing back.
Select the probability distribution you want with the directional arrows. Then confirm by pressing OK to go to the next step.
You have the choice between 3 continuous distributions and 2 discrete distributions.
Type the value of the parameter(s) then select the Next button and press OK to go to the next step.
At the bottom of the screen, you will see a description of the requested parameters.
In the table below, the parameters requested for each distribution are reminded.
|Probability distribution||Requested parameters||What value to enter|
|Binomial||(, ) : number of trials and success probability||(natural number, real number in )|
|Uniform||(, ): bounds of the interval||(real number, real number)|
|Exponential||: parameter||non-negative real number|
|Normal||(, ): mean and standard deviation||(positive real number, non-negative real number)|
|Poisson||:parameter||non-negative real number|
You can now read the result of the probability calculation.
You can modify the type of bounds for your probability calculations:
The last option only concerns discrete distributions.
To do so, follow the instructions below.
You have changed the type of bounds for calculating your probabilities.
You can calculate in from a given probability value.
The calculator will display the value of .
