  Recently, the educational initiative TED-Ed has published a popular brain
teaser coined the 'frog riddle', which illustrates non-intuitive implications
of conditional probabilities. In its intended form, the frog riddle is a
reformulation of the classic boy-girl paradox. However, the authors alter the
narrative of the riddle in a form, that subtly changes the way information is
conveyed. The presented solution, unfortunately, does not take this point into
full account, and as a consequence, lacks consistency in the sense that
different parts of the problem are treated on unequal footing. We here review,
how the mechanism of receiving information matters, and why this is exactly the
reason that such kind of problems challenge intuitive thinking. Subsequently,
we present a generalized solution, that accounts for the above difficulties,
and preserves full logical consistency. Eventually, the relation to the
boy-girl paradox is discussed.
