If anyone is confused with the school board questions. The first one is combination because it said "3 people" which is to say ANY 3 from the 8 will do. The next one says "3 DIFFERENT responsibilities" which is to say it matters which 3 from the 8 gets which unique responsibility. Essentially for these problems pay attention to wording.

When the "bucket" is unique, you never double count. When the "bucket" is not unique, you have to account for double counting. Quick example. If A B C are receiving 2 x $5 dollar bills (bucket). You will end up with A and B , B and A, A and C , C and B. See how A and B is same as B and A since the $5 dollar bill isn't unique and you will need to remove this later. If A B C are receiving a 1 dollar bill and a 5 dollar bill you will end up with: A(1dollar) and B(5dollar), B(1dollar) and A(5dollar) in this scenario you don't have to worry about double counting.

Basically the difference is that in a Permutation, the order matters. In the first example in the video, 3 people were to be chosen out of 10 for 3 UNIQUE prizes (the $20, $10, and $5 prizes). Meaning that the same person who wins the $20 could not also win the $10 or the $5 prize, the prizes are unique. This question could have been made into a Combination problem (where order does NOT matter) by asking how many ways can 3 people out of 10 be selected for the SAME VALUE of prizes (three $5 for example). It doesn’t matter if you win the first $5, or the second $5, or the third $5... you’re getting the same prize. Basically it’s about whether what you’re calculating the probability is for a unique thing or just multiples of the same thing. I hope that helps somewhat.

in permutation/arrangement (20$,10$, 5$ example)order is important i.e it matters to whom we give the first second and third prizes. But the order is not important in combination/selection(same 5$ prize example). so when he took 10*9*8 , he has also counted 3! (or 6) additional possibilities i.e 1st 2nd and 3rd person getting the same 5$ prize . Lets say the prizes are A,B and C(permutation). these can be arranged 3! ways that is ABC,ACB,BAC,BCA,CAB and CBA. but if these are all the same prizes i.e AAA they can be arranged only 1 way(combination).

The first example could be a bit cleaner, cause the way it was expressed I could apply either permutation or combination, depending on the understand; In a group of 10 people, a $20, $10 and $5 prize will be given. How many ways can the prizes be distributed? In case I assume these three prizes are going to be distributed in a draw/lottery way, I would apply on it a combination (10 choose 3), but if it was said the context as a race for example, so I would understand it as an ordering thus applying the permutation (10 permute 3).
@danielschaben5 жыл бұрын
I see that a race would make it clearer. In my mind I am seeing who gets each prize like a first second third. $20 is first, $10 is second, $5 is third. Actually when I made this video, I thought it would get 10 views a year.... not 1000s per day...... it is a strange video to be my most popular. I though my Permutation video and my combination video would be more popular. Both use cleaner examples with cleaner explanations.

i am really confused. Take the example "locker combo" firstly the point of this comment is not that locker combo should be locker perm i already got that cleared. Continuing, if your locker "combo" is 5432 and you enter 2345 it will not work, because order does matter in a permutation, right? Then why does a permutation have more results than a combination? If this locker would also open with 2345 then there should be more results, correct? And then I also don't understand why there's only 1 answer and how I'm supposed to plug in that for an equation nPr??? or for cPr? basically what im saying is why do permutations have more results than combinations if order is relevant in perms and certain options will be removed, where as in combination those options will be kept as choices? I can see it in the formulas, but I don't know truly know why perms have more results. also...for 4:45 and 6:00 why are they not the same answer? Can't you interpret the 3 people chosen as the ones with responsibilities? This makes my head hurt. please help i have a major test with probability being 1/4 of it and it is pretty soon.
@danielschaben3 жыл бұрын
Sorry I have not been replying in a short period of time. I have lots of excuses. Thank you for giving me such a well thought out question. This is a lot to unpack. In a locker combo where your have four combinations that can all be the same number, for example 0000 is a legitimate possibility. and there are 10 symbols that can go into each spot in the proper order from left to right.... Using fundamental theorem of counting we would have 10*10*10*10 possible combinations for this locker key. Or 10,000 possible values. This is neither a combination or permutation. It is a simpler problem of the fundamental counting theorem. I can see now how my video is confusing. A permutation means we pick the combination in order and then cannot reuse the thing we picked. So you would get 10*9*8*7. Or 10p4 or out of 10 things we choose 4 where order is important and we cannot repeat a symbol (so 0000 is no longer a possible locker combination) now we have 5040 ways to choose the locker combo and indeed 5432 would be different than 2345. In the case of the word combination. which should not be confused with something you do with your locker, as it depends on the devise you use.... In my mind the mathematical definition of a combination is a permutation where order is not important. In this case if you get any number correct in any order you will unlock the locker and again 0000 or 5555 is not a possibility. Which I am not sure of a mechanism in the physical world that would produce this..... an any rate 5432 and 2345 would be the same code and unlock the locker.... In this case you would divide 10*9*8*7 by the number of ways to rearrange the 4 numbers (4*3*2*1) so 5040/24 = 210 so now we are down to 240 possible values. I am not sure I am helping you here, but you have given me yet another angle to approach these problems. This is a great example to show the difference between the three things we are talking about. the fundamental counting Theorem, Permutation, and Combination. Those are the big 3, and in my experience the only way to truly understand them is to get down and dirty working tons of different types of problems and finding your own understanding. There are two things to avoid in this world and both lead to self destruction. Always avoid knowledge and money you didn't work your ass off for. Or in other words as a positive. Always work hard for your knowledge and money, so that they are truly yours and only one can be stolen from you. They have to kill you to steal the other, and it is not stolen, just lost.
