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), O₁ = (N, C),
and O₁ = (N, N). Suppose that probabilities are P(O₂) = 0.81, P(O₂) = 0.09, P(O3) = 0.09, and
P(0₁)=0.01.
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).
