Hi, I'm calling.
- 00:02 - 00:04
And today we're gonna be talking about the vision Whole
- 00:05 - 00:09
principle. So the pigeonhole is on artificial habitat that human
- 00:10 - 00:11
created for Beijing.
- 00:12 - 00:14
So it's like pigeon net, but created by human.
- 00:15 - 00:17
So imagine a problem like this.
- 00:18 - 00:20
We have pre three vision holes, but there are four
- 00:21 - 00:25
vision. If anything, one of the whole would have.
- 00:28 - 00:30
So it's gonna be like this.
- 00:31 - 00:32
The first I will have a pigeon.
- 00:34 - 00:38
Then the second hole will have another vision, and the
- 00:38 - 00:40
last one we have to vision.
- 00:42 - 00:46
I'll be thinking, Wait, this just common sense And it
- 00:46 - 00:49
doesn't always like that the first time I have zero
- 00:50 - 00:52
pigeon. The second one might be Grant with four pitches
- 00:52 - 00:54
in there, and the last one might be zero is
- 00:55 - 00:57
not always going to be like this example right here.
- 00:58 - 01:02
So the thing with vision whole principle is that it
- 01:02 - 01:07
stated that if there are more than and pigeon but
- 01:08 - 01:11
only end number of holes, then there will be somehow
- 01:11 - 01:12
with more than n piss.
- 01:13 - 01:18
Mhm. So in simple tear, if there are more vision
- 01:18 - 01:22
than holes, some who have more than one vision so
- 01:22 - 01:26
back to the other example, There will be cases where
- 01:27 - 01:29
some of the whole might be different from the one
- 01:29 - 01:30
that I provided.
- 01:30 - 01:34
It might be 00 and four, but the same principle
- 01:34 - 01:37
apply, and we can see that one of the whole
- 01:37 - 01:39
has more than one vision, which is the last one
- 01:39 - 01:43
for so on to the strategy of how to deal
- 01:44 - 01:45
with vision.
- 01:45 - 01:45
Whole problems.
- 01:46 - 01:50
First, we identify what is the whole second we identify,
- 01:51 - 01:52
what is the pigeon?
- 01:53 - 01:54
And third, we find the answer.
- 01:56 - 01:59
It might seem confusing at first, because how do you
- 01:59 - 01:59
apply this?
- 02:00 - 02:01
This is just pitching flying into holes.
- 02:02 - 02:04
Well, that's what we have.
- 02:04 - 02:07
Examples. No moving on to the example.
- 02:08 - 02:11
The 1st 1.5 year is if we have 20 pairs
- 02:11 - 02:15
of socks and we're in like a dark room, how
- 02:15 - 02:18
many sucks Do you have to take to get to
- 02:18 - 02:18
the same kind?
- 02:19 - 02:24
Yeah, so picking itself blindly in the dark room if
- 02:24 - 02:26
you pick the first one is like a star shape
- 02:26 - 02:28
socks, and the second one is like a hard one.
- 02:29 - 02:31
It's not to have the same kind, so that might
- 02:31 - 02:32
not very a word.
- 02:33 - 02:35
So at least how Maney songs you have to take
- 02:35 - 02:36
to guarantee that you have a pair of the same
- 02:37 - 02:41
kind. So this is where pigeonholed a principal comes in.
- 02:42 - 02:43
First you identify what the whole is.
- 02:44 - 02:49
So the whole list the type of socks, so it
- 02:49 - 02:52
will be like a star type or heart type.
- 02:53 - 02:56
And if we take the 1st 20 out, there might
- 02:56 - 02:57
be the chance off.
- 02:57 - 03:00
All 20 of them are different kinds, so they're all
- 03:00 - 03:02
in different holes, so there won't be appear.
- 03:04 - 03:05
The bitch in here are the socks.
- 03:06 - 03:07
So we have toe.
- 03:08 - 03:13
See, there are 20 hole and so we need at
- 03:13 - 03:14
least more than 20.
- 03:14 - 03:16
So 21 is the closest number.
- 03:17 - 03:19
So we need at least 21 socks to get appear
- 03:20 - 03:23
because the 1st 20 might all be in different hole.
- 03:24 - 03:27
But the 21st one is going to be the same
- 03:27 - 03:28
as one of the prior 20.
- 03:30 - 03:32
So we're now guaranteed have appeared on the 21st one.
- 03:34 - 03:35
You can say that you could get lucky and get
- 03:36 - 03:39
the right pair in your second one, but that's not
- 03:39 - 03:40
how so.
- 03:40 - 03:42
We just got to deal with it and get 21
- 03:43 - 03:47
sucks. So more application to the original principle.
- 03:49 - 03:52
So if you have a deck of 52 car and
- 03:52 - 03:57
the cards are indifferent to Spain, keep diamond and heart.
- 03:58 - 03:58
It would take five card.
- 03:59 - 04:02
The first four card might all be from different, different
- 04:03 - 04:03
whole, which are different.
- 04:05 - 04:09
See, the fifth cards have the same seat as one
- 04:09 - 04:11
of the prior whole one of the prior card.
- 04:12 - 04:14
So now we have two cards with the same seat.
- 04:15 - 04:19
A different scenario is that if we have 32 people
- 04:19 - 04:22
in the party, at least two of the people have
- 04:23 - 04:26
the same birthday as in the day, from the first
- 04:26 - 04:26
to the 31st.
- 04:28 - 04:33
Because the first 31st 31 people, they will all might
- 04:33 - 04:35
have different birthday from the first 2 to 31st.
- 04:37 - 04:39
But the last one, we have the same one as
- 04:39 - 04:41
one of the people inside a part of a four,
- 04:43 - 04:43
and that is it.
- 04:44 - 04:45
That's the vision whole principle.
- 04:46 - 04:47
Thank you for listening, and that's it.
