Different types of people may make different decisions facing the same level of risk. Therefore, before making a decision, the decision-maker needs to first measure the risk. For example, the probability of high demand for OB service is 40 percent. The expected profit of high demand is $2 million. The probability of low demand for OB service is 60 percent. The expected loss of low demand is $1 million. Based on this information, how do you measure risk?Could you say something about expected values, standard deviation, or variance? How these concepts are needed in measuring risk?referencing Lee, R. (2019).Economics for healthcare managers (4th ed.).
