The administration is pulling these head ache files at random, looking at them and putting them back in a pile. The pulls from the pile can be repeated. What is the probability of the event that the first two selections are allmoderate cases?Could you explain and show out the math to this? How could you apply this to a presentation you may be giving at another facility who does not have this info?
