You are walking through a first 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 males and females congregate randomly. What is the probability both frogs are male?
