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 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.

I found this in my textbook, hopefully it helps Corollary: Let n and r be nonnegative integers with r ≤n Then C(n, r) = C(n, n − r)

Imagine you have 10 people and are choosing 2 of them to go outside. Another way to think of the problem is to imagine you have 10 people and you choose 8 of them to NOT go outside. It's counting the exact same thing, just from the other perspective. I hope this makes sense!

nah but with regard to probability, you don't care if heads come first or heads come second. The base is that it's a 50% chance. You don't say that "if I flip a coin and get tails, there must be a 100% of getting tails." This is purely incorrect so order doesn't matter here.
