Explore the sample space more uniformly

The big advantage of Mobius is having random variables in the question, so that students get given different questions. However, when it comes to picking those random variables, Mobius has a habit of choosing pretty much the same ones for quite a while. On a choice of two, it would not surprise me to get the same one 7 times in a row. This results in students being asked the same question after all. The distribution of questions among the available possibilities should be more even.

    Hi Jessica!  I would be curious to see a particular example.  Are you using the built in algorithm functions like rint(), range(), etc.?
