00:00:06
hello everyone, glad to see you again on the
00:00:09
qwerty channel and today we continue to
00:00:11
study mathematics with you, in particular
00:00:13
we’ll talk about such a thing as how to beat
00:00:15
roulette, but before we talk about it,
00:00:25
let’s agree what
00:00:26
roulette is, how sleighs are played, and so
00:00:28
on this is approximately all the rules,
00:00:30
just in case, let me remind you, I will talk
00:00:32
about standard European roulette, that
00:00:33
is, this is a circle that is divided
00:00:35
into thirty-seven identical sectors, of
00:00:37
which 18 red 18 black, the
00:00:40
numbers from 1 to 36 are written there, respectively, and
00:00:43
one sector is green fat,
00:00:45
respectively, if the ball gives out
00:00:46
to Nazir then the casino takes all the bets,
00:00:49
let everyone lose, but if it
00:00:51
falls on a specific number, then
00:00:53
either this one will play, but Maurice bet on it, or the
00:00:55
bet, for example, could be on the light on
00:00:57
red, or for example on even numbers,
00:00:59
or on numbers that are multiples of three, or on the world
00:01:01
from 1 to 12 I actually want bets, but
00:01:04
how is the winnings distributed in this
00:01:06
case, but again, the most standard
00:01:07
system is this: let’s say that I bet 1
00:01:10
ruble and put it on red, in this
00:01:13
case it returns me 2 rubles, the profit is not
00:01:16
equal to one ruble because 1 was not given
00:01:18
back to me two the same bet on
00:01:20
black the same bet on even and
00:01:22
odd when I bet on 18 positions out of
00:01:25
these 37 they return me double in
00:01:28
places if I bet on 12 positions that is
00:01:30
on 1 12 or on divisible by three and
00:01:33
so on there respectively, they return the
00:01:35
troll’s bet if I
00:01:37
bet a ruble, they return 3 of my bets,
00:01:39
and so on, if a
00:01:41
specific number is left,
00:01:42
for example, one and it falls out there, it does
00:01:46
not return 36 times my bet, that
00:01:48
is, if I bet a ruble, it gives me 36
00:01:50
rubles, then the question arises Is it
00:01:52
still possible to beat a casino and if so,
00:01:54
how,
00:01:55
but I think if you open any entry on the Internet like
00:01:57
something like how to
00:01:59
beat roulette, you will find a bunch of articles
00:02:01
that will tell you what it is,
00:02:03
of course, you can do it, and so on,
00:02:05
but I will analyze probably the most popular
00:02:07
strategy today, I will show that if you are
00:02:09
a little familiar with mathematics, there are
00:02:11
such things to conduct degrees
00:02:12
and the more popular strategy of playing against
00:02:16
roulette is called nightingale or
00:02:17
in another way they are called doubling, I think
00:02:20
many have heard about it, the essence of it is as
00:02:21
follows, let’s say you bet one ruble
00:02:23
on black if the bet played won
00:02:26
if you didn’t play the ruble lost and
00:02:28
then you bet 2 on black if the bet
00:02:31
played then how much do you win 2
00:02:33
rubles but you lost the ruble in the previous
00:02:35
step then you only need a ruble
00:02:37
if you lost then you lost more
00:02:40
2 rubles of this 3 bet 4 on black if
00:02:43
he wins again in profit
00:02:45
lost bet 8 and so on
00:02:48
it is clear that sooner or later the black one
00:02:51
will come up and well, it may not fall out
00:02:53
indefinitely, which means you will always have your own
00:02:55
ruble after a certain
00:02:56
number of games and so on it
00:02:59
would seem that it would be great or not, but in
00:03:01
fact, if I carefully figure it out,
00:03:03
there will be some problems. The first problem is
00:03:05
that the casinos arrange
00:03:06
they limit the bet, in the sense
00:03:09
that you cannot double the bet
00:03:11
indefinitely, to understand
00:03:12
the casino and also know this strategy, it
00:03:14
would be strange does not respond to it,
00:03:15
therefore, according to the casino standards, you know that the
00:03:17
smallest bet at the table
00:03:18
differs the most from the largest one, let’s say ten
00:03:20
times, so you can double your ruble
00:03:23
once, get 2 rubles, then again,
00:03:24
8 rubles again, and you can’t double it again, the
00:03:27
bet is 16 already it is impossible to understand
00:03:29
that the first bet may not be a ruble,
00:03:31
there are 10 rubles 100 rubles a million rubles
00:03:32
please, but still the largest
00:03:34
the smallest will differ
00:03:35
several times the second point, but in
00:03:38
fact, in fact, let's think
00:03:40
about this and how often
00:03:42
sequences of the form occur in general there, I don’t
00:03:44
know, 10 times in a row are red, some
00:03:46
are starting to say that
00:03:47
this strategy can be simplified, so let’s
00:03:49
wait until nine times red comes up,
00:03:51
well then it’s unlikely that it’s 10 because the
00:03:53
probability that 10 times in a row
00:03:55
looks red, if you roughly count to the
00:03:57
probability of getting red 1 2 1 2 in
00:03:59
10 one thousand twenty-four there are
00:04:01
few chances here for reds in a row, so
00:04:04
let’s wait for 9 reds in a row and just
00:04:06
bet on black, well, we’ll almost
00:04:08
certainly win,
00:04:09
you bring good luck so that everything on black
00:04:12
always turns out to be stolen, but here there is a
00:04:14
so-called substitution of concepts, yes, that
00:04:16
is we are changing the concept of the probability of
00:04:17
conditional probability, what am I
00:04:20
really talking about when you have waited for 9 reds in a
00:04:21
row, then you then look not at
00:04:24
the situation there will be 10 in a row, but the situation of
00:04:27
whether there will be 10 in a row, provided that there have
00:04:30
already been 9 in a row and in this case
00:04:32
sometime with the fact that 10 will come up red is
00:04:34
actually exactly the same 1 2 that’s about the same
00:04:36
as for the previous ones, that is, the
00:04:38
ball actually does not have a memory and
00:04:40
just like a Taurus, throw a
00:04:42
coin, what is the probability that your
00:04:44
coin will land heads up 10 times in a row
00:04:46
Well, you are very very small, and now
00:04:49
let’s assume that someone has been waiting for you for
00:04:51
9 times in a row on the powerwall, but he
00:04:53
stays in the throw for a long time and here’s how to
00:04:55
do it, what is the probability that you
00:04:57
will also make a mouth 50 percent
00:05:00
before either heads or heads 10 times? tails
00:05:01
therefore, in fact, this is also a lie
00:05:04
that if you waited for a long
00:05:06
series like there are 9 red 10 black and so
00:05:08
on, then the next one will definitely not be
00:05:10
red or odd, in fact, with the
00:05:12
same percentage recipe there will be either a
00:05:13
red flank
00:05:14
for the sake of no but One more point is the
00:05:17
concept of mathematical expectation, let’s look at it with you
00:05:19
and understand why this concept
00:05:21
generally debunks the whole game in the wheel,
00:05:22
what is the mathematical expectation, in
00:05:25
fact, roughly speaking, this is the winning
00:05:27
that on average you expect to play this
00:05:29
or that game, if you put it into words
00:05:31
also a roll, that is, let’s say I
00:05:33
have such a simple game, let’s say I don’t know
00:05:35
for you, play a coin and it comes up either
00:05:37
roll or heads, if it comes up and the
00:05:39
robots are not given 200 rubles there, but if
00:05:41
it comes up heads then I give 500 rubles,
00:05:43
that’s how you count in this in games, well,
00:05:46
probably you will all say that no,
00:05:47
because I give t500 and get a200,
00:05:50
while heads and tails fall out equally,
00:05:51
you can calculate more accurately that
00:05:54
to calculate the mathematical expectation you need to
00:05:55
take each situation and
00:05:58
multiply the probability of this situation occurring by
00:06:01
a win or by a loss and add this one up
00:06:03
in this case, the probability is 2 1 2 and
00:06:06
my winnings will be 201 2 by 200 then 100
00:06:09
and the probability of heads is also 1 2 and check
00:06:13
with me 500 means minus by minus 500 and
00:06:16
multiply by both 2 then -250 and then 100
00:06:19
-250 is minus 150 rubles
00:06:21
is the mathematical expectation of this
00:06:23
game, that is, on average for each round of
00:06:25
such a game I lost 150
00:06:27
in relation to roulette, the
00:06:29
same let’s calculate the mathematical expectation of
00:06:31
each bet, for example, I bet on
00:06:33
black in this case, look, I
00:06:35
have 18 fields 37 which I win, that
00:06:38
is probability 18 30 in the game and 19
00:06:42
remaining fields that I lose 1930
00:06:45
winning that well, I win exactly my
00:06:47
own bet, well,
00:06:48
let’s say I bet a ruble, the profit
00:06:50
will be rubles, and it returns two rubles to me,
00:06:52
but I don’t need it, so the profit from one and
00:06:54
multiply by 18 recipes is in plus and
00:06:56
if I lose I also jump ruble
00:06:59
nose in the forest 1930 means we subtract 19 30
00:07:03
minutes by 1 and get minus one 37 that
00:07:07
is, if I play they bet 1 ruble you on
00:07:10
average about games in one 37 rubles for
00:07:12
each
00:07:13
if I bet there 37 thousand rubles, then I
00:07:15
average thousands of rubles for each game about games,
00:07:17
that is, a bet on black is obviously
00:07:20
losing any bet,
00:07:22
pay attention again, it doesn’t even matter
00:07:25
what happened there before, in fact, I
00:07:26
absolutely don’t care because the ball
00:07:29
has no memory and every time the ball
00:07:31
is thrown again absolutely randomly,
00:07:33
this is if the casino is honest and it doesn’t
00:07:36
make fakes until the ball hits the
00:07:39
magnetic ones somehow, as it
00:07:40
would be convenient for the present if, for example,
00:07:42
we described a not entirely honest algorithm
00:07:44
for an online casino, you
00:07:46
would simply analyze what bets were made and
00:07:48
look where it could choose a ball and
00:07:50
every time we would make sure that the ball
00:07:52
gets there so that we have more and
00:07:53
more, for example, but I will read
00:07:56
that we have roulette fairly, but in this
00:07:58
case, absolutely regardless of the
00:08:00
previous results, it increases until it falls out,
00:08:01
so every time for a rough
00:08:03
rio gram game again and every time this
00:08:05
game is a loss, therefore, in fact, the
00:08:07
game of roulette from a mathematical point of
00:08:09
view about the target for any bet, we can
00:08:11
count the same prefixes for one
00:08:13
specific number until absolutely everything, I
00:08:15
won’t count, but maybe look there it
00:08:16
will be equal to the same if you bet,
00:08:18
for example, one on a specific
00:08:20
sector of 1 ruble then when
00:08:23
this
00:08:24
sector appears you win but its probability is
00:08:27
1 37
00:08:28
and you win how much but
00:08:30
accordingly you will be 36
00:08:32
but at the same time you have already given up one to
00:08:35
win and multiply 3535 by one 30
00:08:37
we get 3530
00:08:39
and you lose highlighted 3630 we
00:08:42
because all sectors except one are not
00:08:44
suitable for you and lose by 1 ruble
00:08:45
we get 35 37 minutes of processions about a miracle -1
00:08:49
May 30 court morality in fact what
00:08:52
exhibition you didn’t do doesn’t matter started 1 and
00:08:54
odd on one sector
00:08:56
and two sectors for black for red,
00:08:58
whatever, you still lose to the casino
00:09:00
on average one 30 and once again at the very
00:09:03
end let's repeat a particularly important
00:09:05
detail
00:09:06
that in a particular round you can
00:09:07
win and of course all these sex stories
00:09:09
because I beat you again lekku, they
00:09:12
may well have some real stories behind them,
00:09:15
but this means that the person simply
00:09:18
stopped at some point, he was lucky at that
00:09:20
moment, but this strategy, if I may say so,
00:09:23
cannot work for a
00:09:25
long time because on average and still
00:09:27
lose on average the game is losing on
00:09:29
well, and please don’t forget about it, I
00:09:32
really hope that knowledge of mathematics
00:09:34
will help you in the future to avoid
00:09:35
financial losses, not only when playing the
00:09:37
battery as we discussed, but also when playing
00:09:39
roulette, so everyone subscribe to our
00:09:42
