608 Bayesian Statistics
Suppose the track wants to take 20% off the top, namely, $200,000. Determine the payoff for winning with a $2 bet on each of the five horses. (In this exercise, we do not concern ourselves with "place" and "show.")
Hint: Figure out what would be a fair payoff so that the track does not take any money (that is, the track's take is zero), and then compute 80% of those payoffs.
