The frog pair riddle was featured on TED-Ed, but MindYourDecisions claims the problem was not presented properly. Here is the probability problem: Frogs are equally likely to be male and female, and you can't visually tell them apart. You see two frogs. What's the probability there is a female in the pair if... 1. the pair contains a male frog, and 2. the pair contains a male frog because because you heard a croak that you know is a male croak?
