Wow. Thank you so much for this simple explaination of this!! After I watched the videos that came with my hw, this was a big help in solidifying this topic.
Thank you so much! I had trouble identifying the Permutations from the Combination problems and this video perfectly explained the difference! You are amazing
You are a genius! Your ability to choose interesting examples and explain concepts so clearly (and in a fun way) really is amazing. I admire your work and I think you should consider a career in math education (if you aren't doing so already).
Good video, but I'm confused at the problem at 11:15, the film festival problem. I'm seeing it as a PERMUTATION because of the word "line-up" which to me indicates that they are listed in order of how they will be shown. If I'm wrong, please explain.
I'm a little confused, maybe you could help. Isn't it possible to have duplicated any of the combination choices as shown in this video? Also, when calculating something like license plate possibilities, would that be a combination or permutation? I feel as though it would be combination. I'm going to watch this video again to see if I can plug the numbers to achieve an answer. I'll be calculating with number and letter options based on 7 digit spaces. How would I add in factors for blanks, symbols, or placard plates?
Extremely excellent video as usual, Kolu Math! Thank you for always making comprehensible videos. Just one question - where/how do you record audios? They're so clear!
Using NCR I got an answer of 8,347,680.... if I did my math correctly. Using the combination lock math in the NPR video I got an answer of 78,364,164,096. 36 digits over 7 possible spaces. I enjoy math very much and am trying to learn more and relearn what I've forgotten over the last decade. Any help would be very appreciated. Thank you for your time.
Aah! Sorry! My reasoning is faulty. I realized my mistake after thinking about it a bit :D Your answers are right, but I will let the comments stay for u to clarify, in case someone else comes up with the same doubt :D
The solution to Yevette throwing a B'day party is wrong! The answer will be 24040 different entourages not 2002. Solve for yourself using the basic principal of counting. There are 5 seats in the Limo that needs to be filled by 14 girls. The 1st can be filled by any of 14 girls, following which the second seat can be filled by any of the remaining 13 girls, and so on. Ultimately, yielding, 14x13x12x11x10= 24040 different entourages. It will be 14P5 not 14C5
Thanks a ton. Very easy to understand, and you've made the material entertaining as well which is a huge plus!
thank you, watched like 10 videos before this, you explain so WELL!!!!!!!!
So helpful! I have a hard time with math. Thanks for taking the time to make an interesting and educational video!!
The use of animations in this video are ON POINT man 😃
This was a tremendous help Professor Kolu! Wishing you were my stats professor.

Was having trouble on this concept , thanks for clearing it up !! Great video ! :)
Thank you for clearing this up. It sounds so simple when you explain it, but my professor is very confusing. Keep up the good work!
Wow Sir you are truly a genius and good teacher.

Last I heard, baseball teams have 9 players, not 8. Otherwise great video on Permutations vs Combinations
Really good explanations
*The last problem about baseball*
it looks like you determined only an 8 man lineup? or does the ninth batting spot not matter?

! A good teacher
thank you so much kolu math!!!
Wouldn’t the film festival one be a permutation however?
I LOVE YOU KOLU MATH!!!!!

So helpful. Thank you!
What if someone wanted "fries" and "fries" as the two options? Would be gr8 to see this added to the vid or in another. Thanks!
love the content
I didn't understand the last example. Why it is a permutation?
+ICOD73 Because like he said. There's an order for it.
I love you! Thank you!
love Joe
Thankyou so much!
making me hungry with all this pizza ice cream etc
Nice
Aah! Sorry! My reasoning is faulty. I realized my mistake after thinking about it a bit :D Your answers are right, but I will let the comments stay for u to clarify, in case someone else comes up with the same doubt :D
Thx m8
Savior.
What if I wanted double pepperoni.....
Kolu should be a university Prof
thanks
love you
same as Keeston
The fuck is factorial?
+Diana Ferrer pretty sure it's a number multiplied by every number below it down to one.
ex. 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 8! = 8 factorial
+Rosseriah yup! its that :p

Man you repeat the same mistake in the NJ Film Festival Example!!
@@ArnavBarbaad Nope. You're wrong. Order does not matter--it's a combination.
Thanks
