Permutations and Combinations - Permutions.

Permutations are easy to understand...but take time to get to why we work them out the way we do so you can understand them better. This video also looks at how permutations differ from combinations, and well as looking at simple permutations, permutations with limited spaces, permutations with repeats, and permutations in a circle.

Thank you.  I haven't studied these things for 50 years and have forgotten so much.

[katlin]

OMG dude thank you for this... you earn a sub

It's 2:28 a.m. where I'm from and I just studied this for 3 hours. That's crazy

Great video, really clear and visual explanation. Bring the one on combinations soon!! And add variations please! I have an exam on monday on this stuff.

Thanku so much for ur videos I passed my GED maths with 174 scores

[tonybarfridge]

Do u have any shortcuts for finding part permutations of words with repeated letters? Thanks 😁😊

[rlight]

Nice! Thanks your realy take time to explain it. Thanks for the video I would like to see more videos from you! (Even if this was a long time ago)

In how many different ways can i arrange my n number of spices if i have a k number of spaces in my shelf? =D

[debidattamishra]

why isn't the circle one infinite arrangments since he circle has infinite different points to set the letters at?

[cloudgalaxy]

Why do we divide by the number of rotations in the circle? I just don't get it. Why don't we divide it by 4! or 3! because that's the number of extra combinations per arrangement, right?
I get that we have the formula, but I don't understand the formula.

For the puppy question the answer should be 40, we shouldn't find the factorial for the 3, what if we had the word Tennessee, we will not do the factorial for the n, e and the s.

In d last example y didn't u do 6!/6 like in d second to d last example

[diegislac]

So basically people in a row is just the amount of seats factorial

I think it's flip-flopped, but okay.
