Introduction to Combinations (Unordered Selections)

[hyanbatista]

Very good lesson! I'm from Brazil and I was struggling to understand the reason why the combination formula works, but thanks to you I finally managed to get the whole thing. You're an awesome professor, Eddie! I really appreciate your videos.

I can't believe how understandable your classes are, I wish all teachers were like you, the way you explain concepts, and the feeling you share is simply amazing

I noticed that 10C2 is equal to 10C8, or alternative k from n in a combination is equal. Please explain why this is. Thank you, sir. Btw your videos are so helpful and fun to watch, I used to watch them in my leisure but now they’re my lifesaver.

If i have 5 spots to fill using 4 numbers (non repeatable) then how do i solve 4p5

Disagree...I think it does matter if head comes first versus second...
