Question:
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 O1 = (C, C), meaning that the first patient selected was covered and the second patient selected was also covered, O2 = (C, N), O3 = (N, C), and O4 = (N, N). Suppose that probabilities are P(O1) = 0.81, P(O2) = 0.09, P(O3) = 0.09, and P(O4) = 0.01.
a. Define A as the event that at most one patient is covered.
i. What simple events are in the event A?
ii. Calculate P(A).
b. Define B as the event that the two patients have the same coverage status.
i. What simple events are in the event B?
ii. Calculate P(B).
