Afactnry makes circular dartboards whose diameter is always between 1 and 2 feet. First use the Principle of Indifference to calculate the probability that the next dartboard produced will have a diameter between 1 and 5/3 feet. Call this quantity 0. Then apply the Principle of Indifference to the dartboard's area, and calculate the probability of the equivalent proposition. Call this quantity in.
