On an installment of Who Wants to Be a Millionaire,a contestant had reached the $150,000level.Confronted with a difficultquestion, he eliminated two of the wrong answers but still had no clue as to thecorrect answer.Guessing correctly would have increased his winnings by $150,000 (doubled) and kept him in the game while guessing it incorrectly would have reduced his winnings to only $50,000 (resulting in a $100,000 decrease in winnings).

a) If he elects to quit and keep the $150,00 is he considered risk averse? Why?

b) What would be the best way of going about it and why is it the best way.

Would it be desirable to avoid having criminals - drug dealers or gamblers - own sports franchises? How could this be prevented if the stock of sports franchises were traded publicly?
