As a retired math teacher, I'm sure I regret if I won't comment on this wonderful explanatory video, A truly experienced teacher only can do such wonders... God bless learnohub teachers.. ❤
2nd semester Computer Science student here. Tomorrow I have a math exam and my syllabus has a probability which cannot be done without Permutation and Combination. Thank you so much as this video helped me to quickly revise the permutation and combination within half an hour.😄
You are a remarkable teacher. I'm a First Year BBA student, and I have this chapter in my syllabus. Thanks for clearing out every doubt which i had along the way. You really teach awesome.
Watching your video at 27 after 2 MAs because I skipped maths because I was afraid of making mistakes in Maths. Good thing : my boyfriend with phd in mathematics and a future professor, has praised you whole heartedly, there is nothing in the video that a student cannot understand, it is that simply explained. ❤
I am studying this chapter just one day before exam and it is really helpfull. All concepts are cystal clear may ur channel become more popular thank u
I was unable to understand permutations and combination when I was studying from my book but after watching your video,I am very confident that I can easily solve any of the problems given in my book.... Thank You very much Ma'am...for this marvellous lectuture..🙏🙏
When I saw chapter's name I thought it would be very difficult but in every video when ma'am starts up by saying "crystal clear" It gives me confidence that I can do it and it changes my thoughts about chapter then I thought it's not so hard Thanks ma'am

LOVE LOVE your mathematics one shot videos ma'am. Do try to make one shot videos of all the chapters of Mathematics of class 11 and 12. Thankkk youuuu!
I just don't know how to thank you , you are just a lifesaver just a day before exam..the feeling is different when you get a concept , that was hard to understand earlier, Thank you💯🙏
Mam I LOVE YOU❤️❤️❤️❤️😘..YOU EXPLAINED IT VERY WELL.. MY MATH'S TEACHER EXPLAINED IT 3-4 TIMES IN CLASS BUT I UNDERSTOOD NOTHING..BUT BECAUSE OF YOU THE CONCEPT IS CRYSTAL CLEAR..LOVE YOU MA'AM ❤️❤️❤️❤️❤️😘..THANKYOU
thanks i completed my 12th last year came here to revise the topics. well it was really slow for me but yes if i would be a newbie i needed such videos . nice work mam .
Amazing video ma'am, although I think there is a minor correction to be made. Under the cards' concept, the pack contains the KING, QUEEN, and JACK, not JOKER. Everything else was legit amazing!!
l always found this chapter difficult. but i could really attempt most of the questions in the text book just by watching this video. l just couldn't believe. thanks alot mam
maam ese type ke video kahi nahi milte youtube mei. aur tabh bhi itne short mei saare concepts clear. thanku. ese videos are very helpful jab coaching mei chapter na karvaya ho aur school mei iska test aa rha ho.
my exam of mathematics will commence after 2 days and i would say you are the best educator for quick conceptualization and firm revision ...hats off to you ma'am...aur haan concept hua crystal clear
the 4 I's are the same letters.... if I write IIII or IIII it really does not make a difference, does it? but in the latter case, the vowels are different... so writing AUE is different than UAE or EAU....
In 1988 when I studied in 11th these concepts were hard to understand since you tube wasnt there. Now i am revisiting and revising my concepts.. Thnx once again to be part of classroom...:-)... Even if one doesnt go to school or top end univ, one can still become rocket scientist thanx to such videos and help spread over the internet..!! Gr8!!
Though I m engineering student, I only know the formulas and doing calculations but today fortunately I came across your channel and find a real concept behind ,it had never look me so easy as I find today.... U deserve warm wishes... Thanks mam❤❤❤❤❤❤😊
Abhi corona mai lockdown ki bjah se online classes chl rahi thi yrr such mai vha bilkul bhi toh samaj nhi aaya tk toh ye felling aa rhi h areey bhai yha chl kya rha h 🤪but now the online video or roshni mam is best explanation and by this all my doubts crystal clear thankuu u mam and keep it up ..❤️❤️😍🤗

Hi Roshni Maam, I am preparing for my MBA entrances and due to a non-science background I had a week base of PnC. This video worked magically and hope to solve every question in coming exams accurately. Thanks aton.
That's really a great way to explain the concept of permutation and combination.
Keep doing good!!!🎉
Aap sach me sb students ke liye ek gyan ki ROSHINI ho💖💗💝💟💞❣️🌎🌏🌍🌋🌌🌌🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏 🙏🙏 🙏🙏
I'm in graduation and was getting stuck on questions on probability because of rusty PnC knowledge. Thank you so much for revising everything in such a short time. More power to you ✨✨

LOVE LOVE your mathematics one shot videos ma'am. Do try to make one shot videos of all the chapters of Mathematics of class 11 and 12. Thankkk youuuu!
Blessed to learn from a teacher😇 like u all Concepts are Crystal Clear!!!!!!!!!!!!!!!!!!!!!!
I just don't know how to thank you , you are just a lifesaver just a day before exam..the feeling is different when you get a concept , that was hard to understand earlier, Thank you💯🙏
Mam I LOVE YOU❤️❤️❤️❤️😘..YOU EXPLAINED IT VERY WELL.. MY MATH'S TEACHER EXPLAINED IT 3-4 TIMES IN CLASS BUT I UNDERSTOOD NOTHING..BUT BECAUSE OF YOU THE CONCEPT IS CRYSTAL CLEAR..LOVE YOU MA'AM ❤️❤️❤️❤️❤️😘..THANKYOU

Ur classes are awesome mam ❤️ Iam a student from kerala and iam so worried about permutation bcz,i can't unstand it! Bt u make it simple for me
Amazing video ma'am, although I think there is a minor correction to be made. Under the cards' concept, the pack contains the KING, QUEEN, and JACK, not JOKER. Everything else was legit amazing!!
Damn Trurth Sahi h 😉🙃
l always found this chapter difficult. but i could really attempt most of the questions in the text book just by watching this video.
l just couldn't believe. thanks alot mam

@@sidhanth9509 Dude chill
Explained the chapter in the easiest way, thank you ma'am..
Live long and keep educate us and the upcoming students..
maam ese type ke video kahi nahi milte youtube mei. aur tabh bhi itne short mei saare concepts clear. thanku. ese videos are very helpful jab coaching mei chapter na karvaya ho aur school mei iska test aa rha ho.
my exam of mathematics will commence after 2 days and i would say you are the best educator for quick conceptualization and firm revision ...hats off to you ma'am...aur haan
concept hua crystal clear
Question :- Ma'am why are we not considering repetition of 4 I in MISSISSPPI but considered the repetition of vowels in DAUGHTER?
Same...I also didn't understand it...
Cynthia Kaushik even if u consider it comes out to be 1..... Coz 4!/4! is 1
the 4 I's are the same letters.... if I write IIII or IIII it really does not make a difference, does it? but in the latter case, the vowels are different... so writing AUE is different than UAE or EAU....
My whole concepts of this chapter become crystal clear ma'am😊🙏
.....
...........Thank you so much ma'am🤝😊😘
Concept hua crystal clear ma'am ☺️ ✨ thank you ❤️

How well you speak Mam! It's easy to understand every concept by the way of your teaching. Sweet and informative. Thanks.
Out of all videos on permutations and combinations on youtube only your video is clear and easy to understand, thank you.
In 1988 when I studied in 11th these concepts were hard to understand since you tube wasnt there. Now i am revisiting and revising my concepts.. Thnx once again to be part of classroom...:-)... Even if one doesnt go to school or top end univ, one can still become rocket scientist thanx to such videos and help spread over the internet..!! Gr8!!
