In the final round of a TV game show, contestants have a chance to increase their current winnings of $1 million dollars to $2 million dollars. If they are wrong, their prize is decreased to $500,000. The contestant thinks his guess will be right 50% of the time. Should he play? What is the lowest probability of a correct guess that would make playing profitable?

- Question 2 A potential criminal enjoys a gain of g > 0 from committing an illegal act. If the potential criminal does not commit the act, he gets a gain equal to g = 0. The expected punishment upon conviction is p (e.g. number of years in prison), but there is the possibility of legal error. In particular, if the criminal commits the act, there is a probability r that he will not be punished, and if the criminal did not commit the act, there is a probability q that he will be punished regardless. a. Derive the net gain (i.e. gain minus expected punishment) for the criminal from not committing the illegal act. b. Use your answer in a. to derive the condition for the criminal to commit the illegal act. Show and explain every step of your calculations. c.

- Matrix question: Suppose centuries ago, a group of people lived in an isolated small village. They loved their land and had no incentives to move. Assume that for the job opportunities, anyone living in that village had five options, to become either a farmer, butcher, baker, teacher, or doctor. For simplification, we name the above 5 job types as Option A, B, C, D and E, respectively. It is also known that: Once a resident became a farmer, the probabilities for him/her to continue being a farmer or become a butcher, baker, teacher or doctor would be 50%, 28%, 10%, 10% and 2%, respectively. Once a resident became a butcher, the probabilities for him/her to continue being butcher or become a farmer, baker, teacher or doctor would be 50%, 20%, 10%, 19% and 1%, respectively. Once a resident became a baker, the probabilities for him/her to continue being a baker or become a farmer, butcher, teacher or doctor would be 50%, 20%, 20%, 8% and 2%, respectively.

There are three bidders for the house, Ernie, Teresa, and Marilyn. First Fiddler's does not know the willingness to pay of these three bidders for the house, but on the basis of its previous experience, the bank believes that each of these bidders has a probability of 1/3 of valuing it at $600,000, a probability of 1/3 of valuing at $500,000, and a probability of 1/3 of valuing it at $200,000. First Fiddler's believes that these probabilities are in de pendent among buyers. If First Fiddler's sells the house by means of a second- bidder, sealed- bid auction (Vickrey auction), what will be the bank's expected revenue from the sale? (Choose the closest option.) The closest option is 448, 148. Please explain in details thank you.arrow_forward
