[lone_wolf]

Good Day Sir

Thank you for the awesome lesson.
I would like to ask in an exam how would I know if I am required to use a venn diagram or a tree diagram or just a contingency table to answer my questions (if they didn't state it)? Are there keywords to identify which method to use to solve or all the methods work for any question.

[ncumisakroti]

Thank youu so much sir for this 😭❤ I really wish you could help with Fundamental Counting Principle though .

[cynthiamakhumo]

Thank you sir for your helpful lessons, may you please do fundamental counting principle

[tea]

Sir, may you please make a video on counting principles in probability?

[phindaniadelade]

[CeeDWrld]

Good day sir.Could you please do the last part of probability which is the Fundamental Counting Principle

[naledinale]

Sir i think we need lesson 8, the counting principle, ( factorial notations, repetition and selections) 🙏🏽❤🔥

[aphiwemapuma]

Hello sir, I just want to know why you only used English for the last question? Or can you use any language between the 3?

[mandlovu]

Uhmm sir can you please do a video on how to restrict a domain to make the inverse a function

[Stellah-cw]

Can you please help me on properties and rules of probability
