Would a call to randomNumber be considered including math/logic in one of the included algorithms within the main algorithm for prompt 2c?
Random number generation is not considered math/logic. They could change their mind of course but I think it's unlikely.
I wasn't quite sure myself, and I can see how this is questionable since in AppLab, the "Math" toolbox contains randomNumber() as well as math.random().
I double checked my resources and although I couldn't find anything that explicitly stated random numbers were not considered a mathematical concept, I also couldn't find a single thing that claimed they can be considered a mathematical concept. I agree to interpret this as a "no".
