View full lesson: http://ed.ted.com/lessons/the-last-banana-a-thought-experiment-in-probability-leonardo-barichello Imagine a game of dice: if the biggest number rolled is one, two, three, or four, player 1 wins. If the biggest number rolled is five or six, player 2 wins. Who has the best probability of winning the game? Leonardo Barichello explains how probability holds the answer to this seemingly counterintuitive puzzle. Lesson by Leonardo Barichello, animation by Ace & Son Moving Picture Co, LLC.

Solution: girl eats banana, cat hunts for fish.

Why didn't they just cut the banana into 50% 50% 🤦🏽‍♀️😂

I was really confused about why the order mattered. I obviously didn't pay attention to the beginning of the video.

Player 1 should receive 44 percent of the banana,and player 2 should receive 56 percent of the banana.

Cat have 9 lives girl just 1
Gabriel Yuma (2 месяца назад)
I figured out easier by checking the cons of Player 1 and pros of Player 2: * Player 1 wins ONLY if both dices don't roll 5 or 6. * Player 2 wins if either dice rolls 5 or 6. So: * Player 1 needs both dices' results. * Player 2 doesn't. So: * Player 2 has "two tries" to win and Player 1 "one try".

Why waste time rolling dice if you are so hungry? Just split the banana.

Being player two is pointless because even if you won, cats can't properly eat bananas.🐱🍌

just murder the cat and eat it, let it have the banana as a sign of your magnanimity

This is such a great idea in teaching theoretical and experimental probability! Thanks!

I am not surprised. Cats don't like bananas. They just want others to be miserable

To all these smartass people saying that they would split the banana- You are not funny Its just a thought experiment, not a real life scenario

I thought the probability for player 2 winning the banana was 2/3 Reason: Player two needs a roll of 5 or 6 to win, meaning he has a 1/3 chance to win But since two dice are rolled, the chance for player 2 to win is 1/3 + 1/3 = 2/3

This is beautiful. I especially like the visual showing the probability as a two dimensional square. If we had three dice you could show it as a cube. So what is the probability of four dice? That would be the probability of a fourth dimensional object, no?
nexi nex (7 месяцев назад)
Won't 6 tie? It says higher. 5 and 5 will tie
Get Rekt, M8 (7 месяцев назад)
But but......the chance of getting 5 or 6 is 2/6. 2/6 multiply by 2/6 is 4/36. So the chance of player 2 to win is 4/36 or 1/9 which is higher than player 1(16/36). Am i correct? Or is it? I need to know where is my mistake...
Oksana Nakonechna (7 месяцев назад)
i would give give the banana to the other person because i I HATE EM

Seems like all these probabilities go out the window when I'm playing DnD

Either way, we're both gonna use the banana for the same thing, if you know what I mean...
Mr. Noodle (7 месяцев назад)
The solution? Make a fishing rod.
Lucky The Wolf Dog (7 месяцев назад)
I am so confused. Not by the video, but by the comments. Some say "one person eats the other and banana". Others are saying "the cat doesn't eat bananas". And 50% of the comments are arguing to split the banana. Still, others are stuck how they got the dice in the first place, or why there's only 1 banana. Or why they can't go fishing. (If this comment seemed rude, then no offense to anyone.)

I can see this is educational, but I'd just split the banana with the other.... I'm smart
My Name Is Secret (8 месяцев назад)
At first i didnt understand But then an idea popped into my mind So ... think of it this way if 1,2,3,4 pop only one time player 2 Wins So that means 1,2,3,4 neted to pop 2 Times to give player 1 a victory.if 5 or 6 pops one time player 2 wins

Boohoo! The banana!

Rima Hlehel so you still wouldnt eat the banana if you were starving to death?

Can any1 explain th interest paradox ?
arjun verma (9 месяцев назад)
But how could they play game while they are hungry,they have no power so theoretically they both will die.it is great to fight for a minute and there is 75% chances for the winning of cat practically.

‘1-in-36 chance that ‘1’ will be the highest number’. But, you’re rolling two dice, so the minimum amount you could get would have to be 2, right?

Just eat the darn cat. Asians do it
Nicholas Hartle (10 месяцев назад)
If you make it so player 1 wins if the highest number is 1, 2, 3, or 5 and player to wins if it's 4 or 6, they'll each have a 50% chance of winning. Also, if you use dice with sides that are divisible by 4, you can give the lower 4th and the upper 4th to one player and the middle half to the other and they'll both have a 50% chance of winning.
Jonathan Weir (10 месяцев назад)
Wouldn’t this work no matter what 2 numbers the second person picked.

It's the saddest thing I've ever seen its just a ba and a na
Rachelle (10 месяцев назад)
The chance for player 2 to win = the chance one dice is 5 or 6 (1/3) + 1/3 of the remaining 2/3 for the other dice being 5 or 6 = 5/9 That's how I did it, it's just more confusing to explain.

Why is p2 a furry?
Emily Baltau (10 месяцев назад)
Okay, why don't you just split the banana? Or, maybe, it could just be whoever gets the highest number.

I choose the cat just because it's cute
Huonous (11 месяцев назад)
In that situation I would rather have half a banana than 44 % chance of getting nothing.
abdallatef nsour (11 месяцев назад)
I bet that 99% of people who liked this didn't understand anything,and that they only liked the cat.
Crystal Lin (11 месяцев назад)
Oooooorr, they could be kinder to each other and *share* the banana, considering that they'll both be living there for like 4 days, unless they find water. Say, it would be smarter if it was a glass of water

Why? Why would you come up with such weird rules for a dice game? Why not just say whoever gets the highest number wins?

The cat and the banana are both food. The girl should eat both for a greater chanse of survival.

4 minutes is very long for a 4/6 times 4/6 though :/

I would just save the banana for a human and leave the cat. Seriously, why a cat?

HOW DID THEY HAVE 12 DICE?
jayanti nayak (11 месяцев назад)
Those two r too greedy. They r playing dice🎲 for just a banana🍌 . They can divide it also. Another thing why didn't they get any food except banana rather they got dices🎲.

If you neglect the point of the video, then it would be wisest to use the banana for bait. Then you could use the bait for more bait, and I think there was a test that showed that saltwater isn't actually that bad for you

Simple choke player 1 and take the banana and eat her meat YAY MORE FOOD

Away to make it fair is to use 1,2,3, and 5 for player 1

The democrat player would tax over half the banana away from the successful achiever. And then throw it in the ocean.
