Beyond the Answer

To calculate the expected value for the insurance company, we need to consider the two scenarios: the female survives the year and the female does not survive the year.
  1. If she survives, the insurance company wins the premium: .
  2. If she does not survive, the insurance company loses the policy amount minus the premium: .
Now we use the probabilities for these scenarios:
  • Probability of survival = 0.999544
  • Probability of not surviving = 1 - 0.999544 = 0.000456
The expected value (EV) is calculated as follows:
So, the expected value of this policy to the insurance company is approximately . This means that on average, the insurance company can expect to make about $112.21 per year from this policy after accounting for the risks involved. It’s a nice way to think about risk management in the insurance world!
