The math of permutations and combinations are located in their respective videos (ruclips.net/video/6XWqDezwbaw/видео.html) and (ruclips.net/video/T1CjOkEb1ew/видео.html). This is just 1) a conceptual overview of the difference and 2) so learners know what the math actually means when they encounter it. Thanks! :)
This was very helpful thank you! My teacher just wanted us to magically know the difference because it was "common sense". Thank you for taking the time and effort to create this, it is much appreciated.
Ahh the pressure! :) Hope you found it helpful. And don't break your head...you will need it later and the world wants to keep you around for a long while longer! All the best, B.
Best introductory video on permutations Vs combinations on RUclips ,I understood it properly now after 7 years (school & college) Thanks a ton Prof Brandon you are great.
Brandon, you have a gift. I am very grateful that you are using it to explain statistics in a way that I can easily understand. You are an excellent instructor. My only negative, and it is very slight--use as many visual examples as you can to explain your concepts.
These teachers go straight to heaven! Excellent job at explaining the concepts. The examples were great as well! I really understand it well now. Thank you.
Thanks Brooke! Glad I could help out. Please share with any classmates who may be struggling. Not all professors can explain things very well. Sorry you had to experience that. Keep on learning! 🍎
Hello! Exact order (permutations) will always be in greater number if the numbers are the same. Take the numbers 1,2,3. If I choose all three at once, that is C(3,3) = 1. One group of 3. For permutations it will be P(3,3). In that case I have three choices for the first number, then two for the second number, then one choice for the last number; 3x2x1=6. [(1,2,3);(1,3,2);(2,1,3);(2,3,1);(3,1,2);(3,2,1)].
This is a great video to understand combinations and permutations. I was struggling a bit with my textbooks, but all seemed clear with your video. Thanks By the way, 45 crippled horses disliked this video.
Great video... honestly I think a big part of why this is so confusing is b/c the letters n and r are used. They stand for nothing that's intuitive. If it was T for total and S for sample at least that helps keep the brain on the right track as far as the context of what numbers are being used.
OMG BLESS YOUR SOUL. This made so much more sense than "order matters". Thank you so so much for clearing this up instead of just going over various problems.
My college days were in the early 90's. I use a variety of college level math everyday at work and play. This "basic" video was a very helpful review for me. It is very often a great idea to go back and refresh as if you have never seen something before. This video was perfect. The sedate, professional, style was very welcome, and I look forward to viewing more of these. I just wish I had RUclips back about 1990. :)
Thanks so much for you comment! The true kudos go to people like yourself that have make the commitment to learn. As I say I just try to turn rocks over so people can take a look at what is underneath. All the best and hang in there! - B
For permutations the order does matter...by definition. Permutations are the number of unique arrangements. The exact order of "bca" like you wrote is just a subset of the 6 permutations. In your "bca" example you decided the order ahead of time. There is only one way to do that exact order; bca. So here is a bonus question: how many permutations have "c" as the middle letter? _ c _ ?
In the stock example, I believe the permutations explanation is meant to be: 30 choices for the first month, 29 for the second, 28 for 3rd, 27 for 4th, 26 for 5th, and 25 for 6th. This gives 30*29*28*27*26*25 = 427,518,000 as shown.
Thanks so much!!! I am in an Elementary Stat class online and was having a frustrating time with permutations and combinations. Thanks again your video helped me tons and I have subscribed. I appreciate it!!!
You deserved way more subscriptions,likes, and views. I completed ANOVA and Simple Linear Regressions and the lecure were succint yet very clear. Perfect. By the way, could you please also make lecture series about more complex ANOVA such as Mixed model- ANOVA repeated . Thanks in advance !
HI Samuel! Yes you have hit on one of my biggest gripes about RUclips. All of my videos are on playlists by topic and sequence. But you would never know it right? :( Right now the best way is to go to my channel homepage and find the playlists on the left side. There used to be a right-side fly-out menu that had the playlist but RUclips took it away. No idea why. Take care! - B
Great video series on stats. A little hint for others, who haven't discovered the relationship between P(n,r) and C(n,1). It kan be written P(n,r) = r! x C(n,r) or C(n,r) = 1/r! x P(n,r). That is a linear relationship.
AMAZING VIDEO! Thank you soooooo much! I really appreicate it. :) I also appreciated your pep talk "keep your head up". I needed that tonight! Thanks so much! I'll be looking for your other videos.
Brandon, thank you for putting energy and time in this. You should have someone listen to the video and edit it. On many slides, it is way too long and too much talk instead of a couple of formulas and especially more examples. Edit and cut, as much as you can, and diversify examples etc. thanks
combinations always confuse me because I think of "combination lock" -- where order DOES matter -- a lock with a combination of 7, 20, 35 is different from a lock with a combination of 20, 35, 7 but no mathematically they are the SAME combination ARGH !!! who names this stuff ?
Thank you for the prompt reply! I do agree that permutations should always be greater than the combination of the same argument. What I dont get is why do you call permutation as exact order. Coz order does not matter in permutation afaik. P(3,3) of {a,b,c} is 6 and comes with many different orders like abc, bca,cba etc etc. But if I say "I want the exact order bca", then I take C(3,3) which is 1 . Does this make sense? Thanks
Sir, in the first example if red smiley in 1st place matters then why do we have 3 choices to place a smiley in 1st place? It can only be one that is the red one. I didn't get it. Please help.
Minute 11, how come the amount of exact order be greater than the amount of any order? I believe any order should be P(10,3) and exact order C(10,3). Please correct me if i am wrong. Thanks!

+Brandon Foltz I was thinking that what does finite maths do mean ? btw, the video was awesome!

Literally the best person for teaching stat/probability. The difference finally makes sense.
These teachers go straight to heaven! Excellent job at explaining the concepts. The examples were great as well! I really understand it well now. Thank you.
best way to spend 20 minutes when learning P vs C, thank so much, i see this two counting processes o much clear now thanks to your explanation
Thank you so much! My professor just expected us to understand and never really taught it. Now I understand! :)
Thanks Brooke! Glad I could help out. Please share with any classmates who may be struggling. Not all professors can explain things very well. Sorry you had to experience that. Keep on learning! 🍎

You're a G. Thank you for doing this. It's helping me get through Finite Math in Uni
Learned way more than in my math class, thanks!
THANK YOU SO MUCH. I HAVE A FINAL TOMORROW AND AM BINGING ALL OF THIS. YOU SIR ARE A HERO
I don't really understand the "order matters" until I watched this videos. I'm having a much clear picture now. Thank you, Dr. Foltz.

I'm learning more here than in my finite class
My exam is tomorrow, after seeing this video I feel pretty confident ! Thank you Brandon!
This video just saved my stats grade. Thank you man!
U have made things absolutely clear....Best stats professor I have ever seen...
But I still need to go along way with you..............
Excellent explanation ! A refresher for all who has some knowledge of this topic. A fresher will also enjoy this lecture.
thank you sir...............now my high school doubt has been cleared after 4 years
Same here dude !

Brandon, your videos are really great. I am really bad in statistics and probability, but you explain in a way that everything makes sense. Thank you!
explained a complex topic in such simplicity, you are amazing!
Please make a similar videos on probability!!
Sir, you are really brilliant. You are really helping out a lot of people.

Great video series on stats.
A little hint for others, who haven't discovered the relationship between P(n,r) and C(n,1).
It kan be written P(n,r) = r! x C(n,r) or C(n,r) = 1/r! x P(n,r). That is a linear relationship.
C(n,r) = P(n,r) / r! BODMAS can be confusing to some
@@vishnoor
1/r! x P(n,r) = P(n,r) / r!, right?
a great help, ive been really stuggling at AS maths, Subscribed!!!
THANK YOU!! YOU SAVED MY LIFE. IM ABOUT TO TAKE MY EXAM LATER ABOUT THIS, AND IM VERY MUCH CONFIDENT NOW. ALREADY SUBSCRIBED :)
You just saved my grade dude, thanks
I never got P&C right, you provided an insight. Thank you sir
.
You are most welcome!
AMAZING VIDEO! Thank you soooooo much! I really appreicate it. :) I also appreciated your pep talk "keep your head up". I needed that tonight! Thanks so much! I'll be looking for your other videos.

great job, I finally understood the difference between permutation and combination .
Really excellent teaching - Thank you Brandon.
Very simple and easy to understand. Thank you for the great video.
Thanks for the quick lecture. This is a great study video to help me review before my exam.
Extremely good video. Exactly what I was looking for. Much appreciated :)
Thank you very much! This is definitely helpful for my stats exam in two days :)
Thank you very much sir! Your explanations are so clear and easy to understand. Lots of thums up for you!
Thanks so much for this! Its actually made it really easy to understand! I'll be thinking of buckets in my stats exam tomorrow :)
Thanks so much!! I am a beginner is Stats and struggling!
Thank you for your very informative videos i am glad i found your videos. Your a life saver.
Very helpful. Have a quiz on Wed. Thanks a lot!
Excellent presentation and explanation.
combinations always confuse me because I think of "combination lock" -- where order DOES matter -- a lock with a combination of 7, 20, 35 is different from a lock with a combination of 20, 35, 7
but no
mathematically they are the SAME combination
ARGH !!!
who names this stuff ?
I wonder who xP
12:19 "the odds are much greater for being correct in the second example"
you meant the FIRST example.
Great stuff Brandon, thank you!
thanx a lot. loved it. have subscribed
Aneera Sadiq Awesome. Thank you Aneera!
thank you very much, excellent teaching
Gr8 m4th m8, i r8 8/8.
oh, the nostalgia, classic memes of the past times
Thank you for these Videos!
awesome video!
This helped so much! Thankyou!
Great video! Thanks so much!
this is great but i couldn't believe you can make billions of lineup with only 9 players
Half Blood Prince This is because you have to take into account the total number of players, which is 25 players.
thanks! this video was helpful!
thank you so much. Like your clear explanation.,
wow very nice
aati Ramro( awesome) cha...(Nepal)
Great explanation
Very helpful, thank you.
THANKS DEAR BRANDON...
you give a damn good explanation!!!
thank you so much!
THANK YOU! THANK YOU! THANK YOU!
You are amazing!
its so good lecture
great explanation... really appreciated (y)
Thanks bro helped a lot!
great video sir
Brandon,
I have a question. The videos are information, but my question, what is the formula to determine that large numbers.
thanks. Life saver!
Superb ,I was willing to visualise it.nd I did..
Thanks man!!!! you're amazing! :)
Thank you
Please add many more such videos
I have been breaking my head over this concpet... lets see if Brandon can help me understand this ;)

good
It would be nice to have a link to the next video somewhere
Thank you..
I don't get the last question ( How many investment ) m
Sir, in the first example if red smiley in 1st place matters then why do we have 3 choices to place a smiley in 1st place? It can only be one that is the red one. I didn't get it. Please help.
Someone has probably posted this already but you do have a typo in the video. Should be "You can choose" instead of "You can chose" around 9:25.
thx. I'm in 9th grade and I have an algebra 11 trig exam in a couple days
Yes, but how Permutations vs. Combinations help us in data analysis?
If I have 5 buckets and 10 balls, what is the probability that all 10 balls fall randomly into slot 1?
Well done! :-)
Minute 11, how come the amount of exact order be greater than the amount of any order? I believe any order should be P(10,3) and exact order C(10,3). Please correct me if i am wrong. Thanks!
I honk the vid would be better if you animated the red, blue and green circles when demonstrating permutations and combinations
THANK YOU
