Hello Amanda, yes you are right! As permutation without repetition, our available choices decreases along the way. That's why factorial (!) which is basically just reducing multiplication works here. But of course factorial also being used in different area other than permutation. Cheers! 👍
Hey supervisor! Yes it's consider as independent event just like your math in form 4. The first pick would not affect anything in your second pick. For instance, I keep ask you to pick a ball in front of you, even in your 10th pick, you still have same amount of choices, literally you not even know it's your 10th pick until I tell you so.
Thank you so much! You really help me alot👍
Thank you so much for your support too, TECH H4CK👍 You make my day feel better too!
So factorial is only used for permutation without repetition, can you clarify my understanding?

Boss so the permutation with repetition same as independent event that we learn in Math Form4?

Can you make video for Form4 Add Math Chapter 6,7& 8? Will be really appreciate if you do that❤️
Hi kyllyk, thanks for your support!! Will definitely find some free time for those chapters that you mentioned 👍
