Chapter 4.5, Problem 14E
Cheating on Your Taxes? Suppose 5% of all peoplefiling the long income tax form seek deductions thatthey know are illegal, and an additional 2% incorrectlylist deductions because they are unfamiliar with incometax regulations. Of the 5% who are guilty of cheating,80% will deny knowledge of the error if confrontedby an investigator. If the filer of the long form is confrontedwith an unwarranted deduction and he or shedenies the knowledge of the error, what is the probabilitythat he or she is guilty?

A $150 eReader comes with a warranty from an electronics business that covers theft (T) and accidental damage (AD) . Due to the high expense of repairing an eReader, it is more cost-effective for the business to provide the customer a complete refund to go toward another one. There is a 5.1% possibility that an AD (Accidenal Claim) claim will be made in any given year. Assume there can only be one claim made (not one of each type).Customers who report an eReader as stolen will get a reimbursement for 80% of the item's full price. A Theft (T) claim is likely to be submitted 3.5% of the time in any given year.What is the anticipated financial benefit or loss for the firm on each contract if the warrantee costs $15.95 for a year?(NOTE: Keep in mind that regardless of whether a claim is made, the consumer will pay for the warranty upfront.)
For people who fill the long income tax form with illegal
deductions, every 6 out of 9 know it is illegal, and the
remaining 3 out of 9 did it incorrectly because they are
unfamiliar with the tax regulations. Among those who
filled illegal deductions and know it is illegal, 75% will
deny knowledge of the error. Among those who filled
illegal deductions because of unfamiliarity, 100% deny
knowledge of the error. If the filer filled out the form
with illegal deductions and denies the knowledge of the
error, what is the probability that the filer knows it's
illegal?

- 2. The following situation arises in various situations such as when you are a homeowner. Suppose you face a random loss L in the coming year. You can purchase insurance against the loss L; the premium is double what the insurance company expects to pay out. (This price is in the ballpark of what reputable insurance companies charge. When you're offered an extended warranty or similar product, e.g., when purchasing an electronic device, the premium can be worse; e.g., 15 or 20 times your expected loss.) Let's assume that your loss L will be $1000 with probability 1/10, $100,000 with probability one in ten thousand, and $1,000,000 with probability one in a million; otherwise, your loss is 0. (a) If you purchase full coverage against the loss L, what is your premium? (b) Usually, the expensive part of insurance is insuring against small losses, and I've selected the p.m.f. of L to reflect this behavior. Assume that a loss of $5,000 would be painful to you and much more than $5,000 would…arrow_forward2. Which of the following is not considered a personal risk? a.

The ILIT contained Crummey provision for the benefit of each child.

Lori died in the current year, and the face value of the whole life insurance policy of $2,000,000 was paid to the ILIT.

In a meeting your client says, "According to an article in the New York Times, 57% of large law firms have a mandatory retirement age for a partners in the firm before they retire partners are paid directly for their work that they do and as owners, they are entitled to a share of their profits of the firm.

Your cashier is trying to convince you to open a store credit card and says to you, "In addition to the 60% discount you are receiving for purchasing these items on sale today, you will get an additional 20% off for opening a credit card amount. That means you are getting 105% off!" a. What is the mistaken assumption here? b. Why is that assumption incorrect? c. If you did truly have an 80% discount, explain what should happen when you go to the counter to buy $500 worth of items? Show calculation d.
