What is the answer to the frog riddle?
The problem is simple: You are poisoned and you know that a particular species of frog produces the antidote, which will cure you if you lick it. But to make things more complex, you know that only female frogs of the species have the antidote—males do not.
Is the frog riddle wrong?
Answer: No matter what the probability of a male frog croaking or female frog croaking is, both ways result in the same probability of finding a female frog! The TED-Ed riddle is a classic conditional probability situation.
How to calculate conditional probability?
Conditional probability is calculated by multiplying the probability of the preceding event by the updated probability of the succeeding, or conditional, event. For example: Event A is that an individual applying for college will be accepted. There is an 80% chance that this individual will be accepted to college.
Why is my female frog croaking?
They croak to attract female frogs for breeding, and to warn away other male frogs from their territory. Female frogs think croaking is very sexy. This is why a little critter like a frog can make such loud noises!

How do frogs talk?
Frogs and toads have vocal cords, just like humans, but they also have a vocal sac, which works like an inflatable amplifier. To start calling, a frog breathes in and then closes its nostrils. It forces the air backward and forward between its lungs and vocal sac, so that its vocal cords can make the air vibrate.
Why do frogs suddenly stop croaking?

golden poison frog

Can you solve Ted’s frog riddle?can Ted?
As part of its riddle series TED-Ed, the youth and education initiative of TED, released a video called “Can you solve the frog riddle?” The video presents a riddle about conditional probability and solves it in a simple way.
What is the probability of the TED Ed Riddle?
The TED-Ed riddle is a classic conditional probability situation. Namely, what is the probability of an event A (‘finding a female frog in the clearing / on the stump’), given that a condition B has occurred (“you’re startled by the croak of a male frog coming from a clearing in the opposite direction”).
What is the probability of two male frogs?
As Pc approaches 1, (that is when the probability of observing a croak from a male frog is extremely common) the probability of two male frogs approaches 33%. This corresponds to TED’s solution, though they frame the problem as the probability of at least one female, which is 1–0.33=0.67.
What is the probability of hearing a frog croak?
The single croak two frog paradox: Given the probability of a frog croaking is 0.5, what is the probability of hearing a single croak from (1) ONE frog, (2) TWO frogs. Surprisingly, the same! For one frog, it is obviously 1/2. For two frogs, it is 2/4 (01,10) of (00, 01, 10, 11), or the same 1/2.
