AISubs v3.7
Thank you for your hard work!
Everyone!
Do you know Tokyo University's lighthouse?
It seems like they're pretty smart when you hear rumors about it!
But is it true?
Even if you just randomly write something like "bweh" on a test like that,
there might be a chance you'll get it right!
That's right!
It might be possible for the people here to answer at least one question about the lighthouse!
So, I'd like to challenge you to answer questions about the lighthouse right now!
I'd like the people wearing glasses to ask questions and I'd like you to answer them!
As everyone said,
Tokyo University's entrance exam questions aren't just difficult,
but anyone who understands the textbook will be able to answer them!
So, this time,
there are some simple questions that everyone can understand,
so I'd like you to do it!
Okay!
Then, let's start with the first question!
Okay!
You two will play rock-paper-scissors many times!
If you win with "gu", you'll get 3 points!
If you win with "choki", you'll get 5 points!
If you win with "pa", you'll get 6 points!
You know, like "guriko"!
And if the other person answers "gu", "choki", and "pa" with 1/3 probability,
in other words, if you answer with the same probability,
what is the best strategy?
Please show us!
Huh?
With the same question?
Huh? Aren't you stupid?
Strategy?
Huh?
Can you afford it?
You and I are the same, aren't we?
It's true!
Wow!
Cool!
It's gone!
No, but you know the answer, don't you?
You know the answer, don't you?
That proves it!
(The answer is "choki"!)
Well, I did it, so I'll say it.
If you're fooled and say "no, that's not it",
I really don't know.
I wonder if I should write my answer.
I don't know if I'm in class or not.
This video.
That's true.
I'm looking at the Tokyo University final exam.
What are you looking at?
I studied at Tokyo University!
Great!
So, are you ready?
Well, I can't help it.
I don't know.
I don't know, but...
I don't know what you mean.
From Suda-i-san...
The best strategy...
"all "choki"!
Yes!
Well, if the other party gives you one-third of "gui",
you lose and get minus three points.
But in that case, you don't know anything.
You can crush your opponent's strongest hand, which is the paw, and get five points.
Plus two points, which is the highest expectation value.
Or you can break your opponent's ring finger and little finger and get only "goo".
What if my classmate breaks his little finger and little finger and gets "goo"?
He wants to put his ring finger and little finger in school.
I'll show you the answer later.
I don't know what "goo" is.
It doesn't say how many points you win.
When you win with "goo", your opponent gets "choki".
When you win with "paw", your opponent gets "goo".
That's the rule of rock-paper-scissors.
Kichiya-san, please go ahead.
First of all, please look at the secret here.
When you put out only "goo", your opponent gets "goo" and you get "zero".
If your opponent gets "choki", you get "three".
If your opponent gets "paw", you get "minus six".
If you put out only "choki", you get "plus two".
If you put out only "paw", you get "plus one".
It's good if you can keep putting out "choki" in a row.
But if you do that, you'll definitely lose when your opponent puts out "goo".
It's a waste of time.
"choki", "paw", or "paw", "choki"
When you're ready to put out "choki",
you're more likely to put out "goo" than "paw"
So if you put out "paw" here,
Then you can end one round with "two wins and one loss".
I thought you were talking nonsense.
Why do you say that?
I didn't know what "chances of winning were" meant.
Kichiya-san, please go ahead.
The opponent is a robot, and you're always playing rock-paper-scissors.
I thought it would be better to keep playing rock- paper-scissors with the "rock-paper-scissors robot" and get more points for myself.
So you just keep putting out "paw"
(laughs)
Well, this is, you know,
you can calculate points by
taking into account that you will lose to your opponent.
Is that so?
Does your opponent get points for this?
Yes, well, it's a point game.
It doesn't say "point game" on it.
(laughs)
The correct strategy is
to keep running away from the situation.
Oh!
So, Shibayu and Guntou...
You're different.
(laughs)
It was intuition.
If you calculate this in formula, it will be like this.
Yes, idiot!
What is it?
Ah, but it's a very simple formula.
Really?
What are you saying?
I don't know at all.
See?
(laughs)
Well, in any case,
it was regrettable that we couldn't say whether it was correct or not.
Wow!
Thank you very much!
Wow!
You're welcome!
Well, let's move on to the next question.
It is true that the circumference ratio is larger than 3.05.
I don't know! What is it?
What is it?
This is a pretty famous problem in ancient times.
Is that so? Why is the circumference ratio larger than 3.05?
Can you tell me about it?
That's right.
Don't say it like that!
Once you draw a specific circle and take a specific value,
for example, if you calculate it with this, you will get this.
Well, that's a good hint.
What is it?
Isn't it a string?
I'm sure you're all just telling me, so I'll tell you.
This is the circumference ratio of a circle.
What?
What is it?
I'm trying to figure it out.
What do you mean?
A circle is like this.
If this is 2 and 3, 2 and 2 are 4 and 5.
9 and 9.
It's 4 and 9, so it's 14.
14.
It's more than that.
You're wrong.
You're crazy.
The first hint is this.
Oh!
I've heard of it.
That sound.
It's like a bell.
I remember only the sound of it.
Don't complain.
You're in the third year of middle school, but this is the definition of the circumference ratio.
I know! I know about this formula!
The middle school students who are learning this now...
It's easy!
They'll say it.
The circumference ratio is larger than the circumference ratio.
This is the last hint.
If you haven't used it yet, please use it.
Please use it in honorific language.
Time's up!
Bang, bang, bang, bang!
Let's start with Ryo.
Even if you ask me to start...
I don't know anything.
I thought about it, but it didn't work out.
Let's look at the formula.
First of all, look at this diagram.
This diagram.
The circumference ratio is always constant.
In other words, the circumference ratio is always constant.
3.15 is 0.05 and 3.05 is always bigger than 3.05.
It's not an applause!
But I have a way of figuring it out in one shot.
Yes, you do.
If you overlap it, it's a one-point draw.
The circumference ratio is not 3.05.
I'm glad you're smart.
The answer is...
The circumference ratio is...
When you try to see the length of the bend in the middle of the circle...
You can see the length of the bend in the middle of the circle.
And you can see the circumference ratio.
Wow!
This is the root 10, this is the root 2, and this is the root 10.
You can add and subtract all of them and get the answer.
Wow!
Wait a minute!
How did you like the question about the circumference ratio?
I'm glad I did it.
By the way, how many people can fit in the circumference ratio?
It's quite a lot of people.
Thousands of people.
Wow!
But we're...
1.89 million people.
We're YouTubers with more than 1 million subscribers.
We've only done 10 videos so far.
Yes.
Isn't it 100 times more amazing?
