3. Medical insurance status-covered (C) or not covered (N)-is determined for each individual arriving for treatment at a hospital's emergency room. Consider the chance experiment in which this determination is made for two randomly selected patients. The simple events for this chance experiment are O = (C, C), meaning that the first patient selected was covered and the second patient selected was also covered, O = (C, N), O = (N, C), and O(N, N). Suppose that probabilities are P(0)=0.81, P(O2) = 0.09, P(O3) = 0.09, and P(0)=0.01. b. Define Bas the event that the two patients have the same coverage status. i. What simple events are in the event B? ii. Calculate P(B).
