Question details

The number of Emergency Room visits has increased over the past several years in the United States. One possible reason for this increase may be that people tend to postpone routine health care. This could result in more visits to the Emergency Room. Of all patients who visit an Emergency Room, suppose 22% are seen in less than 15 minutes, 13% are admitted to the hospital, and 5% are seen in less than 15 minutes AND admitted to the hospital. Suppose a patient who made an Emergency Room visit is selected at random.

1) What is the probability that the patient was seen in less than 15 minutes OR admitted to the hospital?

2)What is the probability that the patient was seen in less than 15 minutes but not admitted to the hospital?

3)What is the probability that the patient was neither seen in less than 15 minutes nor admitted to the hospital?
