00:00Okay, let's see, a question came from 10 combination 6.
00:04Okay.
00:05What is 10 combination 6?
00:07So dear, dear, dear.
00:09This is great.
00:1110 combination of which is?
00:136.
00:14So, how much is 10 and 6?
00:164.
00:17So, here we can use 10 combination 4 formula.
00:22And combination 4 formula is this.
00:25n into n minus 1, n minus 2, n minus 3.
00:28Upon 20.
00:29So dear, where do I put 10?
00:32And my answer is 10 combination 7.
00:35So, 10 combination 7,
00:38which will be equal to 10 combination 3?
00:40So, 10 and 7 are different from 3.
00:43And combination 3, we have a formula.
00:46What is this?
00:47n into n minus 1, n minus 2 upon 6.
00:50We put 10, 10 minus 1, 9, 10 minus 2, 8.
00:55Upon 6.
00:57If we cut down, we cut down.
00:58Now, we cut down from the 2, and we cut down from the 2.
01:00This is 4.
01:01It's 3.
01:02So, 3 4 is equal to 12.
01:03That means this is the answer.
01:04And this is our answer.
01:05Now, dear, dear, dear.
01:06Now, as we say, 9 combination 9 is equal to 1,
01:09which is 1?
01:10So, dear, dear, dear.
01:11There, there, there.
01:12There is nine on the bottom.
01:14What will the answer be?
01:16Nine on the bottom.
01:17Why?
01:18When the bottom is the combination of one, it's always true.
01:21Then do the first thing.
01:22If the combination of the 13, what will the answer be?
01:2513 on the bottom.
01:28And when will the answer be?
01:29First, nine on the bottom is eight on the bottom.
01:32How many of the nine and eight is in the bottom?
01:34When it's lower than one, or the bottom of the bottom of the one,
01:38So, if you have a question, you will answer this.
01:40Combination 9.
01:42Now, 13 combination 1 is 13.
01:4413 combination 12,
01:4613 will come.
01:48So, when n combination 1
01:50or n combination n-1
01:52then what will happen?
01:54N will come.
01:56Now, see,
01:58the problem is that
02:00divide the problem.
02:02So, the problem is that
02:04the problem is that
02:06we are going to talk about
02:08ball problems.
02:10If you select
02:12two green and one
02:14blue ball random
02:16find probability of events.
02:18Type 1
02:20What is the problem?
02:22End.
02:24End is the problem.
02:26This is the problem.
02:28End is the problem.
02:30Now, two green
02:32and one blue ball
02:34from back contain five green
02:36and three ball.
02:38The problem is that
02:40we are going to talk about
02:41the problem.
02:42We are going to talk about
02:43ball pieces.
02:44Now, the problem is
02:46type 1.
02:48Now, how many green
02:50are these?
02:52Five.
02:54We will put two with five.
02:56And how many blue
02:58are these?
02:59One.
03:00Three.
03:01We will put three
03:02combination.
03:03One.
03:06Now, my brother.
03:08My brother.
03:09How many total balls
03:10are these?
03:11Five.
03:12Three.
03:13Eight.
03:14Okay.
03:15The total is always
03:16down.
03:17And how many
03:18are these?
03:19Two green and one black.
03:20Total.
03:21Three.
03:22Eight.
03:23Now, my brother.
03:25Five.
03:26Five.
03:27Combination.
03:28Two.
03:29Into.
03:30Multiply.
03:31Three.
03:32Multiply.
03:33Why is this?
03:34This is the end.
03:35This is the end.
03:36The term is the end.
03:37Multiply.
03:38So, here.
03:39Five.
03:40Combination.
03:41Two.
03:42When we start.
03:43Ten.
03:44Three.
03:45Combination.
03:46One.
03:47Three.
03:48Eight.
03:49Three.
03:50Fifty.
03:51Six.
03:52Three.
03:53So.
03:54After that,
03:55a lot of words
03:57are spread.
03:58You what is spreading.
03:59You can all kill.
04:00You should kill.
04:01We've put a knife,
04:02you can all kill.
04:03Do not kill.
04:05Three.
04:06Four.
04:07Five.
04:08Five.
04:09Five.
04:10Five.
04:11Five.
04:12Five.
04:13Five.
04:14Bonле.
04:15Tro...
04:16Five.
04:17Five.
04:18Five.
04:19Five.
04:20Five.
04:21One.
04:22Yes, sir, sir, sir, this is a whole question, but it is not.
04:27Where is it? Where is it? Where is it?
04:29Where is it? Where is it? Where is it? Where is it?
04:31And when the other thing is different, where is it?
04:33Yes.
04:34I have two green balls from five green balls.
04:39I come to the Sahaj, five combinations.
04:42Three blue balls, three combinations.
04:46But, boy, a big thing is that now the floor is a plus.
04:50So, just like eight combinations, three.
04:53We have not left, fifty-six.
04:56Five combinations, two.
04:58Chanaab, chanaab, chanaab, ten.
05:00Three combinations, one, three.
05:03Answer, thirteen upon fifty-six.
05:07So, ball problem scheme type.
05:11When is this? What is the other thing?
05:14And, sir, this concept is not in ball problem.
05:17If there are two different events, then multiply and then plus.
05:22Now, if you select total three balls, at most two are green.
05:28You select total three balls.
05:30So, if you select team balls, you select more than two will be green.
05:35So, find probability of events.
05:37Now, let's see.
05:38Now, let's see.
05:39Let's see.
05:40Let's see.
05:41Let's see.
05:42Let's see.
05:43Let's see.
05:44Let's see.
05:45Let's see.
05:46Let's see.
05:48Let's see.
05:49Of course, when it comes to at-most, it's zero counts as a count.
05:53Now, how many marriages do we have? Four.
05:56But many of us are like zeroes.
05:58There are two things.
05:59It's not the same thing.
06:01That's infinite.
06:03That's not the same thing.
06:06So, at-most, two green.
06:09I mean, the maximum green balls are two.
06:11But it's like zero green balls and one.
06:15Two, it's not possible.
06:17So, let's see.
06:20Green ball is total five.
06:22Five combination with zero.
06:25Now, total three balls are.
06:27When the green ball is zero,
06:28total three is full.
06:30Here, the sum should be this.
06:32How many balls are.
06:34Three are more than three.
06:36So, these are zero and three.
06:38When we take one green ball,
06:41then we take a Bluetooth.
06:42Now, you have to understand.
06:44This should be.
06:45And when we take two green balls,
06:47then we take a blue ball.
06:48This should be.
06:50My brother.
06:51My brother.
06:52My brother.
06:53My brother.
06:54Now, total three.
06:55Eight combination three.
06:56Then, fifty six.
06:58Here, see.
07:00Zero combination is one.
07:02Is one half.
07:03Number one.
07:04Number one.
07:05Number two.
07:06Numbers.
07:07Angels.
07:08That's the combination.
07:09And the combination three,
07:10three.
07:11Five combination two.
07:12Three.
07:13Eight combination.
07:14Ten.
07:15Ten.
07:16Three is a thirty.
07:17Thirty plus forty five plus one.
07:19Forty six upon fifty six.
07:21This is the answer.
07:23So, kids, these are the types of balls.
07:25I have to explain in detail.
07:27Now, let's see.
07:29Another big hammer-tagadas concept.
07:31If you select one green ball from three balls,
07:35wait a minute.
07:37There are two definite questions.
07:39If you select one green ball from
07:43the bag contains five green and three balls,
07:47then one ball can also be done.
07:49If you select one green ball,
07:51the symbol was 5-5-8.
07:53But, but, but,
07:55it's not a choice.
07:57What is happening in this time?
07:59If you select one green ball,
08:07and you want to select three balls total.
08:09You have to select three balls total.
08:11You have to select three balls.
08:13And what needs to be done?
08:15What needs to be done?
08:17What needs to be done?
08:19If you want to select one green ball from five green and three black.
08:23It was very simple.
08:25Green is five.
08:26Total five plus three is eight.
08:27My answer is five by eight.
08:29But, it's not a problem.
08:31It's not a problem.
08:32Let's understand.
08:33One thing.
08:34If you select one green ball,
08:37and you want to select total three balls.
08:41If you want to select three balls out of which one is green.
08:47Out of which one is green.
08:49So, what is the story?
08:51So, what is the story?
08:53So, brother,
08:55total ball in the bag,
08:57five green and three blue.
08:59So, green then I will select one.
09:01Now, total I have to select three.
09:03So, how much will I do?
09:05Two.
09:06Use a little bit.
09:07When in the bag,
09:08two types of balls are green and blue.
09:10Okay?
09:11As long as we are asking,
09:12I have to select total five green and three blue.
09:15Okay?
09:16So, your concept is very clear.
09:19Now, take one green.
09:21What will be the rest of the ball?
09:22Two blue.
09:25Yes, brother.
09:26Eight combination three.
09:27Eight combination three.
09:28Eight combination three.
09:29How many times?
09:30Fifty six.
09:31Five combination one.
09:33Three combination two.
09:35Answer fifteen upon fifty six.
09:37So, this is my answer.
09:39If you select three balls,
09:41Okay?
09:42Three ball select.
09:43But now, what is it?
09:45At least one for it.
09:46The number one.
09:47The number one.
09:48The number one.
09:49The number one.
09:50At least.
09:51Exactly.
09:52The number one is accurate.
09:53For example,
09:54if you learn two.
09:55In the total,
09:56there are five people in the bag.
09:57In the total,
09:58there are five people in the bag,
09:59in which there is nothing to be done.
10:00Now, at least.
10:01In the NAD,
10:02there are minimum 50% of people in the bag.
10:04So, you can always buy 50%.
10:05How many people in the bag?
10:06So, total of the bag?
10:07How many people in the bag?
10:08I will be effective with the two and this way.
10:10100 points are possible.
10:12Now, how many balls we have selected?
10:14Three. At least one green.
10:16That means, the green balls can be minimum one.
10:20Two can be.
10:22And how many can be maximum? Three.
10:24Why not have three?
10:26Because we have selected three balls.
10:28Now, let's understand.
10:32Ah, yes.
10:34Five green, three blue.
10:36One select.
10:38Now, we have to select one green in five.
10:40So, five combination is one.
10:42Now, if there is one green,
10:44then what will be the rest of the two?
10:46Below.
10:50Now, because there are different events,
10:52that's why we have to do this.
10:54Now, let's do it first.
10:56At least one green ball,
10:58one and two.
11:00First, let's do it first.
11:02If there are two balls,
11:04two balls,
11:06one and two.
11:10And then,
11:11what are three balls?
11:12What are three balls?
11:13Green balls.
11:14So, blue balls,
11:16zero.
11:17Okay.
11:18Now, let's do it first.
11:19When this is different even,
11:20this is plus.
11:22I have to explain it.
11:24And I have to explain it.
11:25Otherwise,
11:26this is like a multiplication channel.
11:28Now,
11:29what is the story?
11:30Five,
11:31here is three.
11:33How many are blue balls?
11:35Three.
11:36Five combination,
11:37one,
11:38five.
11:39Three combination,
11:40two.
11:41Three.
11:42Five combination,
11:44two.
11:45Ten.
11:46Three combination,
11:48one.
11:49Three combination,
11:50one.
11:51Five combination,
11:52three.
11:53Two.
11:54High one.
11:55Four.
11:56daddy,
11:57two.
11:59Two.
12:00Two.
12:01Two.
12:02Two.
12:03Three.
12:05both.
12:06Three.
12:08Other.
12:14Two.
12:15Two.
12:17One.
12:20What will be the answer?
12:22We can say simple to say that
12:24You can use n combination with 0
12:26Or n combination with n
12:28What will be the answer?
12:30What will be the answer?
12:32Very important
12:34This was probability of getting green ball
12:36Now tell us
12:38How many probability of green ball
12:40How many probability
12:42This is the biggest
12:44The chance of event
12:46The chance of event
12:48The probability of green ball
12:505 by 8
12:52The chance of event
12:54This is the complementary
12:56Look
12:58The total value
13:00The total value
13:02In fraction and probability
13:04I will minus green
13:06The probability
13:081 by 8 minus
13:108 minus 5
13:12Here the answer is 3
13:14The probability of green
13:16It will not be
13:18The probability of green
13:20This will be 3 upon 8
13:22Very important
13:24Very important
13:26Probability
13:28All the confusion
13:30We will go through
13:32But we will talk about
13:34One person who has 5 green balls
13:36And 3 groups
13:38You know, probability of green ball
13:40It is a successful attempt
13:42Successful attempt
13:44Divide by total
13:46Green ball is 5
13:485 is 5
13:49But the total number of balls
13:505 plus 3
13:528
13:53It will be 8
13:54It will be 8
13:55This answer is 5 upon 8
13:56This answer is 5 upon 8
13:58What answer?
14:00Probability of green ball
14:025 upon 8
14:04The big problem is
14:06Green ball is the probability
14:08Here
14:095 upon 8
14:11So dear
14:12If you ask the question of blue ball
14:13If you ask the question of blue ball
14:15Then I see blue ball
14:17How many?
14:193
14:20And the total balls
14:21Then the total balls
14:225 green
14:23And 3 blue
14:248
14:25So blue ball
14:26The probability of blue
14:27The probability of blue
14:283 upon 8
14:30So my brother
14:32This answer will come
14:33I will explain
14:34completely basic
14:36My dear dear dear dear
14:38In how many ways
14:40Can letter of the word
14:42Coca Cola
14:43Pela
14:44Be arranged when
14:46All letter
14:47To be used
14:48So
14:49Now
14:51I will start
14:52I will start
14:53How many letters
14:54Are there?
14:558 letters
14:56So
14:57Actually
14:588
14:59But
15:00C is
15:013 times
15:02So
15:03We will divide it
15:043 times
15:05It is also
15:063 times
15:07It is also
15:083 times
15:09What will we do?
15:11Now
15:12We will open 8
15:138
15:147
15:156
15:165
15:17So
15:18I will stop
15:19Because
15:201
15:213
15:22Vectorial
15:23And
15:241
15:253
15:26Vectorial
15:276
15:28It is also
15:29Now
15:30We will remove it
15:31Our answer
15:32O
15:33L
15:34And
15:35L
15:36And
15:37We have not written it
15:38This is my answer
15:39To
15:46The
15:48Web
15:49Of
