Lottery B pays $3,000 with a probability of 0.3, $8,000 with a probability of 0.4, $12,000 with a probability of 0.2, and $15,000 with a probability of 0.1. Which of the following is true? A) A risk-averse person would definitely prefer lottery A to lottery B.B) A risk-averse person would definitely prefer lottery B to lottery A.C) Whether a risk-averse person prefers lottery A to lottery B depends on his degree of risk-aversion.D) A risk-averse person would prefer to pay $50 to switch from lottery B to lottery A.E) We do not have enough information to judge whether any of the statements listed in A-D, above, are correct.

Brain tumors in children are rare: the base rate is only about 1/10,000. A child with a tumor is very likely to have occasional headaches: 99 out of 100 do. But there are many other reasons a child can have a headache: of those who do not have a tumor, 1 in 10 have occasional headaches. 1. Given that a child has occasional headaches (H), what it the probability that he or she has a brain tumor (T)? Show your work. 2. Name a behavioral bias that may occur when estimating the probability that your child has a brain tumor. Would this bias lead to under-or-overestimate that probability? Explain. 3. Among children with headaches (H), 999/1000 will ultimately be fine (F). Suppose that a physician using a simple test can correctly determine whether the child is fine or not in 95/100 of children with headaches. Given that the doctor after performing the test gives the patient a green light (G), what is the probability that the child really will be fine? Show your work.. Page 1 of 1 175 words…

A construction company needs to move lumber onto the roof of a building. If the lumber falls and hits someone it will cause $1,200,000 in damage. Assume that company must choose between the following levels of precaution: Spend $500 and the probability of an accident is .05 Spend $5,000 and the probability of an accident is .01 Spend $8,000 and the probability of an accident is .008 Spend $10,000 and the probability of an accident is .003 If the construction company is strictly liable for the costs of the accident, how much would they spend on precaution? A. $500 B. $5,000 C. $8,000 D. $10,000
