Wow this has helped me so much! I am preparing for the TJ test and I didn't really know much about probability, combinations, and permutations. This was a descriptive video that I could actually understand. My teachers will skip few steps that we should know, but sometimes you get lost in the problems. You explained every step and I really appreciate you teaching me.
@@Mathispower4u Thank you, I was really frustrated when I wrote that and if it wasn't for your videos, I would be lost in space for ever. Seriously, thank you for what you do, these videos are done so well.
3!4!5! does not equal 60! He is dividing by (2!2!2!) = (2*1*2*1*2*1) = 8. In the following problem, he divides by (3!4!5!) = (3*2*1*4*3*2*1*5*4*3*2*1) = 17280. While this number is large, it is much smaller than 60!.
this guy is a legend. I learn more in 10 minutes from him than I ever did with my teacher ❗❗
Cuz all they do is send us straight to him and teaches us nothing
you are a God send...makes so much more sense the way you explain things..

Excellent method of explaining it to middle school students. Thank you!
Thank you for this. Seriously, so thankful.

6:37 holy smokes! that many arrangements from 28 people in a group of 5?
How can you tell when order does or doesn’t matter?
Very good explanation
I found the video very helpful..Thank you
Good job.
I really wish you would go a bit slower with the calculator part, I can’t see when you input the factorial button.
Sorry about that. You can slow the speed of the video. It is one of the options if you click on thereare the bottom right.

your magician thank you
great, thanks.
at the 9:36 mark you divided by 8 instead of 8! so i think that's a mistake because in the following problem you do divide by 60!
3!4!5! does not equal 60!
He is dividing by (2!2!2!) = (2*1*2*1*2*1) = 8. In the following problem, he divides by (3!4!5!) = (3*2*1*4*3*2*1*5*4*3*2*1) = 17280. While this number is large, it is much smaller than 60!.
how would you do this without a calculator?
paper znd pen and LOTS of time
I have a crush on you
that's not cool
