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 ex periment in which this determination is made for two randomly selected patients. The simple events are O ₁ = (C, C), meaning that the first patient selected was covered and the second patient selected was also covered, O ₂ = (C, N), O ₃ = (N, C), and O ₄ = (N, N). Suppose that probabilities are P ( O ₁ ) = .81, P ( O ₂ ) = .09, P ( O ₃ ) = .09, and P ( O ₄ ) = .01.

a. What outcomes are contained in A , the event that at most one patient is covered, and what is P ( A )?

b. What outcomes are contained in B , the event that the two patients have the same status with respect to coverage, and what is P ( B )?
