Suppose a life insurance company selts a \( \$ 300,000 \) i-year term life insurance policy to a 20-year-old fomale for \( \$ 210 \). According to the National Vital Statistics Report, \( 58(21 \) ), the probability that the fomale survives the year is 0.999544 . Compute and interpret the expected value of this policy to the insurance company. The expected value is \( \$ \square \) (Round to the nearest cent as needed.)

The Deep Dive
To calculate the expected value of the life insurance policy for the insurance company, we will consider the two possible outcomes: 1. The female survives the year. 2. The female does not survive the year. Let’s denote: - \( P(\text{Survives}) = 0.999544 \) - \( P(\text{Does not survive}) = 1 - P(\text{Survives}) = 0.000456 \) If she survives, the insurance company collects the premium of \( \$210 \). If she does not survive, the company has to pay out \( \$300,000 \) minus the premium received, resulting in a net loss of \( \$299,790 \). Now, we can compute the expected value \( EV \): \[ EV = (P(\text{Survives}) \times \text{Gain if survives}) + (P(\text{Does not survive}) \times \text{Loss if not survives}) \] Substituting the values: \[ EV = (0.999544 \times 210) + (0.000456 \times (-299790)) \] Calculating: 1. Gain if survives: \[ 0.999544 \times 210 = 209.88 \] 2. Loss if does not survive: \[ 0.000456 \times (-299790) \approx -136.50 \] Adding these together: \[ EV = 209.88 - 136.50 = 73.38 \] Thus, the expected value of the policy to the insurance company is approximately \( \$73.38 \). The expected value is \( \$ 73.38 \).
