I am doing an assignment for a class in college where we have to write an arithmetic encoder / decoder in Java.

In this video, it shows how to set up / define all the variables required for the algorithm. I am unsure how to set the values for the probability of each symbol (Pi).

If anybody could explain how to work out the value of R, ri and Pi I would really appreciate it!
