Can you solve the frog riddle?

You're stranded in a rainforest and you've eaten a poisonous mushroom. To save your life you need an antidote excreted by a certain species of frog. Unfortunately only the female frog produces the antidote. The male and female look identical but the male frog has a distinctive croak. Derek Abbott shows how to use conditional probability to make sure you lick the right frog and get out alive.
