Math Problem Statement
Solution
To find the expected value of the profit for the insurance company, we can use the following formula for the expected value :
From the provided information:
- The profit can be either (if the woman dies, the company pays out the benefit) or (if she survives, the company keeps the premium).
- The probabilities associated with these outcomes are and .
Let's substitute these values into the formula:
Calculating each term:
Now, summing these results:
Thus, the expected value of the profit is $73.

Here are five related questions to expand your understanding:
- What factors influence the probability values in life insurance policies?
- How would the expected value change if the probability of survival increased?
- What impact would a higher premium have on the expected profit?
- How would the calculation change if there were additional outcomes (e.g., partial payouts)?
- What is the significance of expected value for insurance companies?
Tip: Expected value helps companies understand the average outcome over many similar policies, guiding pricing strategies to ensure profitability.
