180. An insurance policy covers losses incurred by a policyholder, subject to a deductible of 10,000. Incurred losses follow a normal distribution with mean 12,000 and standard
deviation c. The probability that a loss is less than k is 0.9582, where k is a constant.
Given that the loss exceeds the deductible, there is a probability of 0.9500 that it is less
than k.
