Level Up Just By Eating

One-fifth room-Part 1

-Synopsis up to the previous time-

We ended up passing through five rooms.

However, one of them is filled with deadly poison gas.

A scroll for detoxification-I was given a scroll, but there were four scrolls.

Somewhere in one room, you have to pass by round waist.

Which room should I go through with a round neck?

-Synopsis, up to here-

We stood before "First Room".

Two meters high. A two-meter-wide shallow rectangular stone door.

Like a type that opens from the middle, a thin line is visible in the center of the door.

"But this door ... how can I open it?"

When I tweeted, the door glowed white.

Mutsu bills come out.

I heard a voice.

If you lose, everyone will die in an instant!

I do not want to see the cruel development of breaking friends, Fortine-sama shines!

It was a pretty evil spirit.

Roller mutters.

"Consider stochastically ...

Should the last room be passed without scrolling? "

"That's no good."

"Why ?! Isn't that the best in probability ?!

If there are poison gas chambers in the first four rooms, can we break through with zero risk? ! "

“…………”

I didn't want to go straight in and looked at Laura with the eyes of a idiot.

"Why is that face ?!

Is this not wrong? !

Is there a probability? ! "

"If you limit yourself to pinpointing only this time, isn't Laura right? ...?

Probabilistically-if you just say "

"I also think that Laura is correct if I only say stochastically."

"Zena!"

(Yeah.)

Marin is grateful, but everyone else agrees.

Apart from Laura and Lindis, up to a decent pair of Rorona and Femir ...?

I was a little confused, but soon calmed down.

(Even on the earth, the theory of probability began to be properly discussed around 1600.)

It is probably from the 1900's that the average people start learning.

I explained briefly.

"I will explain it with lots in a way that is easy to understand.

Five lotteries have only one hit. Is the probability of winning the first time one fifth? "

"Yes!"

"Um"

"Yes!"

"If the first piece is missing, there are four remaining lots.

The odds are a quarter. ''

"Yes!"

"However, in order to reach this" quarter ", it is necessary to draw" losing lottery "in the first time."

"If you win the first time, all the rest is lost!"

"In other words, the 'probability of a second hit' is calculated by multiplying 'fourth of the probability of catching a loss' by 'quarter of the probability of hitting the second time-four-fifths times quarters'. Become one "

"So that's it……!"

"I'm always impressed with Kema's insights ...!"

"Wait a minute! Lolo-chan, Femi-chan, how do you know ?!

I didn't know. ! The story suddenly falls at the last minute!

You didn't even know Lindis, right? ! "

"It's exactly what Laura says!

"Quarter" and "quarter" are too technical terms! "

(……… hidden.)

Marin, a young girl, goes behind the two who fly the boos.

"Three-to-three! It's an equal number for a majority!"

"What do you do to put numbers in even small children ..."

"Every child or adult is one person. There is no difference in value. Don't you think so?"

Laura suddenly turned to the goddess and said that.

It is quite annoying that a perfect goddess full of compassion in painting.

I pinched my cheeks.

"Myuey ~~~~~~~~~~~~~~~~~~~~"

"This is just like a lottery.

The chance of hitting a poison room is the same no matter which room you choose.

But to put it simply, a room with poison is-- ''

"Maybe the last room"

"By common sense, 'breakthrough without risk' is impossible ..."

Rorona and Femil nodded to my opinion.

"So, which room would you pass without scrolling after all?

As far as I heard, it didn't matter if I used it in the last room. ''

"... the fourth room."

"Fourth?"

"Ah"

I used scrolling.

Dress yourself in the door bills, dressed in anti-poison magic.

Everyone imitated me.

The voice of the announcement resounds.

Indeed this room-!

Guogogogo, the door opens.

I have used scrolls unnecessarily!

I go straight ahead.

(Titete)

A small roller followed.

"Hey Kema, why is it the fourth?"

"In terms of possibility, the fourth is the lowest."

"Who?"

"This game-The room chosen by the player who played by inertia is either" last last "or" first first "

"What do you mean?!"

"First, the last is the risk-free route."

"Yes!

I feel like everybody wants to choose this! "

"On the other hand, the" first "is the 80% chance of surviving.

If you are determined and open, this is the only one. ''

"Sure ... yes.

If you can't decide in one-fifth, it's difficult to decide in one-fourth. ''

"People who play by inertia also use scrolling for the second door.

Also used for the third door.

Fourth use.

In the third, when I said, "Let's decide here," my fellows rejected it (.........)

"I knew that the first and last were dangerous and dangerous, but ... what's the fourth safest?"

"The point is that Goddess Fortina said that 'the trial also has the meaning of securing human resources.'

"Who?"

"As I said at the beginning, if you play this game by inertia, there are only" last "or" first "rooms that can be reached without scrolling.

Even if you try to open in the third or fourth, there is a high possibility that you will fail because of "breaking friends".

I mean-"

Rorona said, interrupting me.

"The ability to open the fourth room without scrolling is the intelligence and judgment that allows you to think calmly even before this unusual trial.

Only parties with overwhelming charisma who can convince their friends.

It is hard to imagine burying such human resources in a "trial" that involves securing human resources.

I want to say that! @Kema! "

Rorona's eyes were shining brilliantly.

I completely respected me.

"I was thinking so much ...

Femil also stares at me with respect.

And Laura said of course.

"In other words, can you break through this test --- thanks to me?"

“…………………………?”

"That's right ?!

Speaking of charisma!

I thought a lot about Kema, but everyone will follow me only if I have charisma!

If you look at the stories so far calmly and consider them, it will be such a story? ! "

"Nara ne"

"Fugy!"

I had a small upper in Laura's little jaw.

Got it! A light sound was heard.

――This “reading” was completely correct.

The poison gas room was the last room.

If we passed through the fourth room without scrolling, the story was over.

Nevertheless, we would use scrolling in the Fourth Room.
