Sir in second last question you multiplied the total number of words 5 factorial by the answer so in the last question why don't we multiply the total number of people 5 factorial to the answer as well?
best video on permutation and combination. loved it. understood the concept finally and able to attempt all the questions. thank you very much. please make more videos like this for different topics.
in Q9, P(7,3) * P(4,2) gave the same answer as the actual...so it is just coincidental or it works this way because I did P(7,3) * P(4,2) to get the right answer
I know it's a year late. But you solved it correctly. The tutor has made a mistake. 1. They used C instead of P 2. They assumed 5! ways of rearranging the letters instead of 5!/3!2!.
ques 5 me 6 into 5 into 1 hoga na kyuki last me 1 possibility h wo theek h pr hundred place pe to 6 possibility hui na fir 1 choose hogya to tens place pe 5 possibility hogi fir ones pe 1 possibiliy to ans 30 ayega m i right sir plz tell me ?

Sir on 6:49 , l’m not sure that are we not supposed to multiply the 151200 by the arrangements of the Ss which is 4! To get (I’ve) 3628800.
Yes you are right
Yesssssssss
At q 2 may iv is the correct answer
Cauze 4 s is also there so £10/£3£2£2×£4 will be there
£= factorial
Sir in second last question you multiplied the total number of words 5 factorial by the answer so in the last question why don't we multiply the total number of people 5 factorial to the answer as well?
Because in last question order doesnt matter.. if names of men and women were given then we would have multiplied by 5!

Broo in question 2 u also need to multiply 10!/3!2!2! by 4! as we also need to arrange the 4 'S' ???
Ya you are right
No it is a part of it already!!!!! I lost marks for this controversy😂😂😂😂
No....... We have taken 4 'S' as a single number
SSSS = 4!/4! = 1
Har question ka logic alag hota he permutations me

Lecture is good
14:00 It is not permutation? but sir has solved it as combination?
This is wrong, because say we have consonants FGTYHKU and Vovels AEIU
then we have _ _ _ ; _ _ --> it cane also be FFF-EE which is permutation? right
