Two coins are tossed; what is the probability that the outcome will be one head and one tail? The answer to this question for classically distinguishable coins is, of course, one-half. If, on the other hand, the coins are indistinguishable, the answer is usually given as one-third or one for coins which are respectively described by Bose–Einstein or Fermi–Dirac statistics.
