El (Type an integer or a decimal.) Suppose a life insurance company sells a $200,000 one-year term life insurance policy to a 19-year-old female for $280. The probability that the female survives the year is 0.999558. Compute and interpret the expected value of this policy to the insurance company. The expected value is $|:|. (Round to two decimal places as needed.) An investment counselor calls with a hot stock tip. He believes that if the economy remains strong, the investment will result in a prot of $60,000. If the economy grows at a moderate pace, the investment will result in a prot of $10,000. However, if the economy goes into recession, the investment will result in a loss of $60,000. You contact an economist who believes there is a 30% probability the economy will remain strong, a 60% probability the economy will grow at a moderate pace, and a 10% probability the economy will slip into recession. What is the expected prot from this investment? The expected prot is $:|. (Type an integer or a decimal.)
