(A) 0.55 (B) 0.73 (C) 0.80 (D) 0.87 (E) 1.25

215. Losses under an insurance policy are exponentially distributed with mean 4. The deductible is 1 for each loss. Calculate the median amount that the insurer pays a policyholder for a loss under the policy. (A) 1.77 (B) 2.08 (C) 2.12 (D) 2.77 (E) 3.12

216. A company has purchased a policy that will compensate for the loss of revenue due to severe weather events. The policy pays 1000 for each severe weather event in a year after the first two such events in that year. The number of severe weather events per year has a Poisson distribution with mean 1.

217. A company provides each of its employees with a death benefit of 100. The company purchases insurance that pays the cost of total death benefits in excess of 400 per year. The number of employees who will die during the year is a Poisson random variable with mean 2. Calculate the expected annual cost to the company of providing the death benefits, excluding the cost of the insurance. (A) 171 (B) 189 (C) 192 (D) 200 (E) 208

220. A motorist just had an accident. The accident is minor with probability 0.75 and is otherwise major. Let b be a positive constant. If the accident is minor, then the loss amount follows a uniform distribution on the interval [0, b]. If the accident is major, then the loss amount follows a uniform distribution on the interval [b, 3b]. The median loss amount due to this accident is 672. Calculate the mean loss amount due to this accident. (A) 392 (B) 512 (C) 672 (D) 882 (E) 1008
