Two IGCSE examples of Permutation and Combination

I think both of these questions apply to SPM and IGCSE Add Math students. However, both of these question is getting from CIE IGCSE syllabus.
Permutation - 4304 - s15 - 12 -Q5
Combination - not sure is from Text book or past year paper.

The combination one is actually O level syllabus/GCE. If you are interested it is actually 4037/N04/paper1/Question7 or in short 4037/N04/1/7

It’s 5 different places to put the 2 symbol, so multiply by 5

Teacher, you made a mistake at 2:25. It's permutation, not combination. If I use combination then I get 28 instead of 20160.

[@mathew_pang]

yeah i think i also said is nPr , but somehow i wrote nCr by mistake. thanks for letting me know
