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 are o, = (C, C), meaning that the first patient selected was covered and the second patient selected was also covered, o, = (C, N), 0, = (N, C), and O4 = (N, N). Suppose that
probabilities are P(0,) = 0.81, P(O,) = 0.09, P(0,) = 0.09, and P(0,) = 0.01.
(a) What simple events are contained in A, the event that at most one patient is not covered?
O A = {(C, C), (C, N), (N, N)}
O A = {(C, C), (N, C), (N, N)}
O A = {(C, N), (N, C)}
O A = {(C, N), (N, C), (N, N)}
O A = {(C, C), (C, N), (N, C)}
Calculate P(A).
P(A) =
(b) What simple events are contained in B, the event that the two patients have different statuses with respect to coverage?
O B = {(C, C), (C, N)}
O B = {(C, C), (N, N)}
O B = {(C, N), (N, C)}
O B = {(C, N), (N, N)}
O the empty set
Calculate P(B).
P(B) =
