00:00Babbette was invited to participate in a famous TV game.
00:04If she answered correctly to all the questions, she would win a prize of 1 million euros.
00:09For the first round, she had to associate the bird on the image with the right shadow.
00:13Can you help her?
00:25Yes, it's the fifth shadow that she has to associate with the right shadow.
00:28Yes, it's the fifth shadow that she has to associate with the right shadow.
00:33For the second round, she had to solve this riddle in the form of a riddle.
00:36Look at the image.
00:37Can you help Babbette to discover the following two letters?
00:41And why?
00:51The answer was obvious.
00:53The following two letters were E and P.
00:57Which are the initial letters of the word and, followed by the word why.
01:04Then, the TV game animator projected this image right in front of her.
01:08He asked her if she was able to find the hidden number in the image.
01:12Can you guess what number Babbette answered?
01:15The answer was E.
01:23The number 2 was hidden right there, in the middle.
01:29As Babbette was doing very well,
01:31the TV presenter decided to make the riddles more difficult.
01:35He asked her how many circles there were in this image.
01:38Can you help her?
01:46This one was a bit more difficult.
01:48But there are 6 circles.
01:51Babbette was getting closer to the last round,
01:53so the TV presenter decided to make things even more difficult.
01:57He chose a riddle that 90% of people don't know how to answer.
02:01Look at this image.
02:03The TV presenter asked Babbette to cut the main object of the image into 4 equal parts.
02:08How could Babbette solve this riddle?
02:12There you go.
02:13All you have to do is to divide the big shape into smaller versions of itself.
02:18For the last round, the TV presenter improvised a riddle.
02:22He asked Babbette,
02:24On the way to Berlin, I met a man with 7 women.
02:27Each woman had 7 bags.
02:29Each bag had a number on it.
02:31Each bag had a number on it.
02:33Each bag had a number on it.
02:35Each bag had a number on it.
02:37On the way to Berlin, I met a man with 7 women.
02:40Each woman had 7 bags.
02:42Each bag had 7 cats.
02:44Each cat had 2 kittens.
02:46How many people went to Berlin?
02:48Could you help Babbette to find the answer to this riddle?
03:00Well, only one person went to Berlin.
03:03The person who saw everything.
03:05He brought 1 million euros.
03:08Dan opened a time portal
03:10and released a group of mutant ants inside his laboratory.
03:13The 4 humans remaining in the lab had to escape
03:16before the ants caught up with them.
03:18To do this, they had to cross an old rope bridge
03:21suspended above a huge ravine.
03:23According to Dan's calculations,
03:25the ants would catch up with the lab team in 17 minutes.
03:28He had to find a way to get everyone across before that.
03:32Dan was the fastest of the group.
03:34He could cross the bridge in one minute.
03:36The assistant of the lab, Becky, could cross it in two.
03:39But the concierge and the professor were slower.
03:42The first needed 5 minutes
03:44and the second needed 10.
03:46How could they get to the other side safely?
03:49Knowing that the bridge could only support 2 people at a time
03:53and that each group had to bring the only remaining lantern to light the way.
04:05Here's how it all works.
04:07Dan and Becky cross first, carrying the lantern.
04:10After 2 minutes, they are both on the other side of the bridge
04:13and Dan, the fastest, comes back running with the lamp.
04:16Then the professor and the concierge cross together.
04:19It takes them 10 good minutes.
04:21In total, 13 minutes have elapsed.
04:23Becky grabs the lantern and rushes to the other side of the bridge
04:26to help Dan cross.
04:28With the remaining 2 minutes,
04:30Dan and Becky reach the other side again
04:33safely, just in time to cut the rope and save their skin.
04:39Alice had a terrible argument with her best friend Jenny.
04:42They were supposed to go hiking together
04:44but after this argument, Alice decided to go alone.
04:47After a long walk, she ended up finding a place to stay for the night.
04:51She took all the precautions to spend a night of camping safely
04:55but the next morning, when she woke up,
04:58she discovered that her supply bag was empty.
05:00Someone had stolen all the food inside
05:03and had left only the bag.
05:05Look at the picture.
05:06Can you find out who the culprit is?
05:17Although there were animal prints on the ground,
05:20none of these animals would have been big enough
05:22to reach Alice's bag hanging from the tree.
05:25But, hold on, hold on, what is it?
05:28It looks like Jenny's bandeau.
05:30She must have followed Alice and decided to play a trick on her
05:33by stealing her vibes.
05:36Pierrot had had enough of the bustle of the big city
05:38and moved to a quieter village.
05:40He opened a small cafe
05:42and his establishment quickly became very popular.
05:45His coffee made a sensation in the region.
05:47Farmers, hipsters and other barstards
05:50came from all over the country to taste his famous cappuccino.
05:53He even won a prize for the best coffee in the region.
05:56Until one night, someone broke into his shop
05:59and stole his annual stock of milk and coffee.
06:02Pierrot decided to investigate by himself
06:04and questioned four suspects.
06:07Dylan, a painter,
06:09said that he was not in the village that night.
06:11Leila, who was working at the cafe,
06:13said that she had spent the whole night
06:15working on a personal project.
06:17Anessa said that she was rehearsing a choreography
06:19for the next New Year's Eve performance.
06:21And Gaston, a farmer,
06:23said that he was taking care of his animals.
06:25Take a look at the suspects.
06:27Can you determine who is the culprit?
06:39They certainly did not have the best alibis,
06:41but the culprit is clearly Vanessa.
06:43She said that she was rehearsing
06:45for the New Year's Eve performance,
06:47but look at these flowers!
06:49It's still spring!
06:52For a school competition,
06:54100 students received
06:56a number between 1 and 100.
06:58Each student had to enter
07:00a classroom that contained
07:02exactly 100 boxes
07:04randomly numbered from 1 to 100.
07:06Inside each box,
07:08there was a piece of paper
07:10containing a random number,
07:12including between 1 and 100.
07:14Each student had to enter
07:16the classroom alone
07:18and find the box containing
07:20the piece of paper with its number.
07:22To do this, the student was not allowed
07:24to open a maximum of 50 boxes.
07:26They were instructed
07:28to leave the room
07:30exactly as they had found it,
07:32and they could not communicate
07:34with another student
07:36once they had left the place.
07:38If all the students managed
07:40to find their numbers
07:42on the pieces of paper
07:44inside the boxes,
07:46they would each win 100 euros.
07:48But if only one of them
07:50managed to find all the students' numbers
07:52and win the prize...
08:02This riddle is clearly
08:04not obvious,
08:06but let's see how it could work.
08:08If each student was looking
08:10for their random number,
08:12each student would have a 50% chance
08:14of finding the box containing their number.
08:16The calculation is quite simple,
08:18since they are allowed to look
08:20inside 50 of them.
08:22However, the probability
08:24that each student finds their own number
08:26by observing this random strategy
08:28is virtually non-existent.
08:30To increase their chances
08:32of finding their respective number,
08:34they would need a better strategy.
08:36The students could use
08:38what is called a loop strategy.
08:40Once in the classroom,
08:42they would have to go directly
08:44to the box containing their number.
08:46The number inside
08:48would probably not be theirs,
08:50but it doesn't matter.
08:52They would have to discover
08:54the number inside the box
08:56and look for the box with the same number on it.
08:58And so on.
09:00They would then have to continue
09:02until they find the paper
09:04with their number on it.
09:06This strategy means that 31% of the time,
09:08all the students could find their number
09:10and win the prize.
09:12This is not a huge probability,
09:14but hey, at least they would have
09:16a lot of fun trying to solve all this.
