Probability distributions

In this experiment, we can simulate the occurrence of random events which can have one of several distributions: Any of these distributions can be assigned to the random variables x, y, or z.

After the random variables x,y,z are defined, a new random variable w(x,y,z) can be formulated.

Rules for forming expressions for w:

This allows the user to express the following sort of problem:
