Combinatorics 1.3 Combinations - The Binomial Theorem

[TinyMaths]

This isn't the first time I'm coming across your channel, but I've gotta say, you are up there when it comes to 'clarity'. Some of your stuff helped me get through last year which was my first year of college as a middle-aged mature student. Now I'm in my second year you're probably one of the teachers I'm going to focus on just because of the way you are articulating these concepts. It has taken me a long time to figure out which teachers I can grasp and hopefully with the right approach to study I'll make it through. Thank you!

Thank you for posting your videos! I would be lost without them.

cannot find anyone better than you in explaining combinatorics!

Thank you! You have helped me clear up many issues I was having for my probability class.

Your videos helped me a lot for nsejs preparation thanks ma'am

im already 2 weeks in my discrete math module and i was in so much dread because i couldn't understand combinatorics. thank you for these videos its helped a lot!

This youtube channel is so underrated ☹️

28:05 It should be (a+b)^n and not (a+b)^n-1.

Just a question for PR.2: The binomial theorem. The coefficient of x^3y^8 in the expansion of (x+y)^11 isn't it be 12 choose 3? According to (a-b)^(n-1) so for (x+y)^11=>(x+y)^(12-1)

The combinatorial proof does not seem like a rigorous proofing method. It seems as though I could "prove" a false identity by just selecting a word problem that happens to be an instance where said identity produces a true result.

Could you please tell me what textbook are you using for the course material?
