i feel s1 questions are a bit confusing, they are not clear in what they want (maybe its because there are some keywords that i need to know or something like that)
how did ur exam go?
how did we know v will be greater than 0.50?
We dont need to know that
can you please solve s1 oct 2022 and jan 2023🙏🙏
I have a question how can there be 3.75 bottles containing more than …. There can’t be 0.75 of a bottle so shouldn’t we like say 3 bottles contained more than … ml ?
In part c , how did you know the v is going to be on the positive side of the graph and not the negative
Because of the probability (area) is 0.2801 so will be on positive side, if it was 0.7 for example it would be on the negative side
@@yaseralshroofi sheesh right, that makes sense thank you
@@yaseralshroofi still doesn't make sense question didn't said tht (V>v n Vv/V
Hi, mr hassan. I want to ask if you have a proper video covering probability? Like, covering a question but you go in depth about the constituents of probability, etc, given that you like to teach via answering questions.
hello pls answer if you u could pls!! you know how you have past paper per topic playlists for IAlevel. the playlists have some very old questions so do they still fit into the new specification or are they a different format (basically should i use them as revision or are they outdated) thank you!!
They are still valid and good for practice... the S1 and M1 syllabus hasn't really changed too much
@@MrHassaansMathsChannel thank you so much!!
How do u know that v is greater than the mean?
Exactly im confused too
how did he know where to place the v
@@ItsKarimM unto 104.9 the prob is 0.975, between 104.9 and v the prob is 0.27 so that means area lesser than v is 0.7 so v Is greater than 0.5
upto*
Ive explained this concept in detail here

Hi Mr Hassaan, have you uploaded the october 2022 paper solutions for S1? Thank you.
I cannot do that... my channel is already under threat of closure... i cannot upload locked papers
@@MrHassaansMathsChannel Oh is it a locked paper sir. No problem then.. Hope it does not get closed. It is a very useful channel.
Hello Mr kindly can you advice me to what significant figure should my answer be to all questions, specifically in normal distribution as in part one i find the answer from calculator not from table please advice my exam in a few days🙏
read 7th bullet point on the first page of statistics1 exam paper. It says "If a calculator is used instead of tables, the value should be given to an equivalent degree of accuracy"
@@bluejay8411 It means I write same value i got as in table?
@@ahmademad5927 honestly I'm not so sure either. I'll ask few friends of mine and lyk
@@ahmademad5927 yes, you are supposed to write values with the same number of decimal places/ sf as it is in the table. And in other questions and generally, write answers in 3sf if they haven't mentioned specifically to round off to something (like 2 sf and so on)
