In order to verify the accuracy of their financial accounts, companies use auditors on a regularbasis to verify accounting entries. The company's employees make erroneous entries 5% ofthe time. Suppose that an auditor randomly checks three entries.a Find the probability distribution for Y, the number of errors detected by the auditor.b Construct a probability histogram for p(y).C Find the probability that the auditor will detect more than one error.

There is a 0.9991 probability that a randomly selected 29-year-old male lives through the year. A life insurance company charges $152 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $110,000 as a death benefit. Complete parts (a) through (c) below. Question content area bottom Part 1 a. From the perspective of the 29-year-old male, what are the monetary values corresponding to the two events of surviving the year and not surviving? The value corresponding to surviving the year is $negative 152−152. The value corresponding to not surviving the year is $109,848109,848. (Type integers or decimals. Do not round.) Part 2 b.
