Consider a simplified example in which all $70,000$ residents in a particular town pay $$100$ a month to the insurance company SecureSure for medical

insurance coverage. The insurance company cannot predict whether a given resident will need hospitalization or how much any individual's care will

cost$.$ Suppose, however, it has data that on average, $10\%$ of the citizens require care each month, costing an average of $$1,000$ each. The expected

average cost of monthly care will be $

per person. If the insurance company sets the monthly

equal to this amount,

it would break even $($on average$).$

In reality, the rates that an individual pays each month vary based on a process known as

$,$ in which the insureds are

divided into four insurance classes. The class, which is based on an insured person's loss expectancy grad, determines the amount he or she pays.

Consider the following example:
