[@sinovuyomchubulo6980]

These lessons are very helpful sir thank you very much, My sister is doing good at both maths and physics because of your hard work....

[@MlungisiNkosi]

I’m so happy to hear that. Thank you so much 😊

[@pjoy_salile5826]

Mr mlungisi your lessons really helped me when I was still in high school 😉😉please continue with this hard work.........Thanks

[@MlungisiNkosi]

I’m grateful to hear that… please recommend to as many matriculants that you know.

[@Tiffany2oo4-s4]

Thanks maybe this time I will pass my supplementary exam

[@DinnyNdoveng-jp6no]

Thanks sir it's absolutely amazing 👏

[@Deathdemon65]

Sir you do a better job then most teachers at school i mean sure they explain but because of how short periods are and time constraint they cannot explain fully thnks to you i understand

[@MlungisiNkosi]

I am in a partnership with all the teachers… Please don’t criticise them

[@Sean-t5j]

Some of us like the video before watching 😅

[@Samkeliswa_2588]

@MlungisiNkosi Sir I don't know if I'm interpreting the statement wrong but I have concern with the tree diagram , are we not suppose to have probabilities for FRIDAY and SATURDAY only.
Why?
We are told to assume that TODAY is FRIDAY right and it raining. So if it is raining TODAY then the chances of also raining TOMORROW (SATURDAY) is 0,8. Then if FRIDAY is not raining then the chances of raining on SATURDAY is 0,3.
So my question is why are we including SUNDAY where else we are given information about FRIDAY and SATURDAY ONLY?

[@SinethembaMamkhuba]

Thanks for the lesson of probability

[@EsihlePamla]

This is really helping we really appreciate

[@MlungisiNkosi]

You’re most welcome 🤗

[@morapedithomas7694]

I suggest that there be consistency in the drawing, in the first path, there are two words, Saturday and Sunday, but in the second path those are not there

To say I’m not excited hearing this would be a lie. Thank you so so much 😭😭😭😭😭😭😭

[@Zaneta-r8p]

Very helpful. Thank you.

[@vuyileqinga4729]

Good day bhut'Mlungisi, your lessons are very helpful, because I was really struggling with probability. Can you please do one or two examples on tree diagram using playing cards, because if they involve cards I really struggle to tackle the questions based on them.

[@MlungisiNkosi]

Hi. I’ll try to involve more examples of that

[@RamonaThabiso]

Mr. Mlungisi, please do videos for the measurement topic for Mathematics 🙏you're the fixer 🔥

Always welcome

Thank you sir 🙌💯

You’re most welcome

[@akhonamunkie]

Sir at 13:35 should'nt the answer of 0.8×0.8 = 0.64 instead of 0.16??

[@akhonamunkie]

Oh nevermind sir, you fixed it

[@MlungisiNkosi]

Thank you 😊

[@mosesmbatyazwa6295]

Sir Mlungisi, I have the same question here, on the last question number e) why is it that we using the formula P(A and B) = P(A)xP(B) if these are dependent events.

Sir I'd like to ask if you did not make a mistake on answering c...
Was it not supposed to be 1-0.3 instead of 0.7?

[@amandashandu880]

Sir...when we will be doing past question papers?

[@MlungisiNkosi]

With time… For now, I want to finish the curriculum.

[@ZINTLEBADUZA]

I really did not understand this one Sir is there another vid for past exam question on tree diagrams

[@MlungisiNkosi]

Did you watch the full lesson?

[@KarieT.]

Sir I don't understand
For Question D.... the probability of it not raining on Saturday is not dependent on it raining on Sunday so why is it 1 minus the probability of it raining on Sunday. Should we not check our tree diagram where at the end there is no rain on Saturday ... where we could other go straight to the answer which is no rain on Saturday would be 0,2 or we could multiply no rain on Saturday times no rain on Sunday plus no rain on Saturday times no rain on Sunday which would still give us 0.2 not 0.3 because the probability of it not raining on Saturday does not depend on the probability of it raining on Sunday because Saturday came before Sunday

[@MlungisiNkosi]

The probability of rain on each day does depend on what transpired the previous day according to the question

[@KarieT.]

@@MlungisiNkosi Yes so the probability of it raining or not raining on Saturday would depend on what happened the day before which is Friday not Sunday sir🙈
