  • Abstract
    A solution is obtained to the problem of finding the minimum of the average number of weighings, using a balance, needed to locate one light coin from among n coins of which n - 1 are genuine and of the same weight. Optimal strategies are determined, and the anomaly that it may be better to work with n + 1 coins rather than n is examined and explained.
