This application is about the binomial distribution.
Using the sliders, you may change the values of:
n (number of trials)
x (number of successes)
p (the probability of success)
If you tick the check-box, you get the cumulative probability.
The app provides a graph, as well as the values for probability P (or cumulative probability), and the value
of the binomial coefficient.
You may also right click one of the sliders and the value of P and select "record to spreadsheet" for there
to get the numerical values of P as the value of the chosen slider changes.
