You are walking through a forest when you hear a croak from a pair of frogs of the same species. You do not know which frog croaked. You know only males of this species croak and are otherwise indistinguishable from females. Croaking is random and independent from other frogs, females and males exist in equal proportion and in arbitrarily large amounts, and frogs congregate randomly and independent of other frogs. What is the probability both frogs are male?
