PMMinimax regret decision

In future you must ask in the Ask the Tutor Forum if you want me to answer - this forum is for students to help each other. The only criteria that uses the probabilities is the expected value criteria. Probabilities are of no relevant when using minimax regret (or maximin or maximax). I hope you are not using our lecture notes without watching the lectures. That would be pointless because it is in the lectures that I work through the examples and explain and expand on the notes. I do explain the various decision making criteria in the lectures.

You are welcome :-)
