A collector has captured thirty-one Anachronism-type small monsters. Each Anachronism-type small monster has 27% chance of being a Phlogiston-subtype and a 47% chance of being an Aether-subtype; it cannot be both. What is the probability that exactly seven of the captured small monsters are Phlogiston-subtypes? What is the probability of all but five of the captured small monsters being either Phlogiston- or Aether- subtypes, with those five being plain Anachronism-type monsters of neither subtype? What is the probability that all thirty-one captured small monsters are either Phlogiston- or Aether-
