Can you please give the example when the P/y and C/y are not the same?
hi, for the AI SL course the values of P/Y and C/Y will be the same.
HELPFUL THANK YOU
You're welcome!
thank you very much bossman. very appreciated
Glad to help
this was very informative thank you so much!
You’re welcome. Glad it was helpful.
Thank you so much very useful
You are welcome
Really helped!! Thanku so much!!
You're welcome!

3:35 why did you put the p value as 0.5 and how to determine it in different questions
the probability of ‘success’ in my example was 0.5 because that was the probability of getting a ‘head’ when a coin is tossed once, or 1/2 as a fraction. Suppose in another question you had rolled a dice four times and recorded the number of times you scored a 5, then the probability of ‘success’ in that question would be 1/6, as that is the chance of getting a 5 when a dice is rolled once. So in general, the probability of success, what you referred to as p value, is determined by a simple probability calculation, determined by what is chosen to be ‘success’ in the question. I hope this makes it clear.
@@mathsican7796 understood, thank you so much sir for making this so clear, respect :D.
thank you very much

If the game is played by paying $1. Then do i have to take net profit to calculate the expected value. And is expected value and expected winnings(or retun) same or different
I’m not sure which ‘game’ you are referring to but you could do it either way. You could calculate the expected return/payout (ignoring the $1 payment) and then compare the expected return to the cost of playing ($1) and work out the net gain by finding the difference. Alternatively you could include the cost of playing ($1) in your expected ‘net return’ calculation, ie subtracting $1 from each ‘payment/return’ value, in which case the result of the expected value calculation is the expected net gain. The ‘expected value’ is just a generic phrase. Whether it refers to the expected ‘payout’ or the expected ‘winning’ or expected ‘net gain’ depends on how you have defined your variable, as mentioned above. I hope this helps, Warm regards
@@mathsican7796 I am not referring to any game I am asking just "if".
So if you calculate the expected winning (ignoring the cost) and it comes to $1 then that would be a fair game. Alternatively, if you subtract $1 from each of the return amounts and then calculate the expected net return and if E(net return) = 0 then that would be a fair game. Either method is fine.
thank you very much

Your slides are really helpful and thank you. Can you please increase the volume of your voice while editing, it is not easy to hear
glad they helped - yes apologies for the lack of volume. Will try to improve on future videos.
Thank you for a very helpful video! I'm currently starting mathematics revision for my final exams and you explained the questions clearly (I especially appreciate manually outlining how to calculate the test on the GDC), it helped me to grasp this area of the material quite fast!
Glad that it helped. Good luck in your final exams.
beautifully explained thank you😭
Glad it was helpful!
Can you explain how you got the angle as 117 at 5:59 please
Hi. The bearing of Edmonton from Calgary is 009, so the bearing of Calgary from Edmonton is 180 + 9 = 189 degrees. The bearing of Churchill from Edmonton is 72 degrees. So 189 - 72 = 117 degrees. I hope that this is a bit clearer than the method described earlier in the video. Regards
@@mathsican7796 thank youuu
Thanks for the very helpful videos. I think there is a mistake. The question in the beginning gives a 5% significance level. However the final answer is that "there is sufficient evidence, at the 10% significance level, ..." Am I missing something?
Hi. Thanks for pointing this out. You are correct there is an error right at the end, however it does not affect the outcome of the test. The test statistic is less than the critical value, so the Null hypothesis is accepted. It should state “that there is insignificant evidence at the 5% level to reject the null hypothesis”. Even if the P-value was compared the the 5% significant level, the conclusion would have been the same - accept H0. I hope these makes it clear and many thanks again.
@@mathsican7796 Thank you for your reply and for making these videos so clear and available on RUclips!
you’re welcome.
tyyyyy smmm this was really helpful oml 😭
Glad it helped!
Really really thank you
You’re welcome
good video keep it up
thank you
Thank u kind, Sir. I really needed to know this for my upcoming year 12 exams (in Aus). The beginning was very helpful as well since my textbook doesn't do a good job of explaining the finance solver function properly.
I’m glad it was helpful and best of luck in your exams
Life saver, THAMK YOU!!!
You’re welcome
why would I believe anything you say when you don't even know how to properly spell Amortization idtio
Amortisation is the British/Non-American spelling. It seems like you are the idiot now...
This is British English, not American English
Thank you! this helped alot
That’s good. You're welcome!
This really helped a lot! Thank you :)
You're welcome!
Underrated!
Thank you! Very informative video!
Glad it was helpful!

Zahra I am your huge fan , you have done a lot of good work on IB math AI course. Can I please have your email address??
helpful. thanks
You're welcome!
You have done a great job Sir.
Thank you 🙏
Thank you so much for your help!
You're welcome!
I have my maths paper 2 in a couple of hours and me and my rooommate Thomas have struggled on this topic - thank you so much for your amazing explanation - you’ve saved our exam!
You’re welcome. I hope your exams went well.
I have my ib exams tomorrow! Thank you for all the useful information you are providing! Very good for revising!
you’re welcome. Good luck in your exam.
Awesome, thank you sir!
You are most welcome.
thank you so much for this it was really helpful !!
you’re welcome 😀
hi when I go to calculate the expected frequencies from the statististics after setting up the matrix it says [not enough elements]
hi, what 2 way table are you dimensioning for Matrix A (the observed frequencies)? If it is 2 by 2 for example, then you will need to enter values into the 4 cells created. I don’t understand your comment “when I go to calculate the expected frequencies “, as you don’t need to calculate them manually. When you press EXE to perform the 2 way test, the calculator will automatically dimension matrix B to be the same as matrix A and it will calculate the expected frequencies for you. The only possible error that I can think of is that you haven’t entered values into all of the observed frequency fields in matrix A. 🤔 You must populate at least half of these fields (the others would be zero by default), before the calculator will perform the test. I hope that this helps.
Thanks for the help
you’re welcome
Hi, I have a statistics 101 exam… my question is can I solve everything with my cg50?
Sorry, Im not familiar with the 101 exam… but checking out the syllabus online I’d say that you could most of the stuff on your cg50
Invested for 4 years why 4*1=4 in it other videos u did 4*12=48
it’s because in this example the interest is compounded ‘annually’, which is only once a year - so the value of k is 1. In the other video the interest was compounded ‘monthly’, which is twelve times a year - so k was 12. I hope that this makes sense.
Thank you. The questions have helped understand the concept a lot better. 🙂
Glad it was helpful!
Thank you this helped a lot
You’re welcome 😁
u teach well but u look like johnny sin's father
Dear kind Sir, Thank you so much, truly. I have a math exam tomorrow and you are saving me countless hours of stress. The manner in which you explain these topics is incredibly easy to follow, relaxing, and clear. Your voice is also exceptionally soothing. I hope you will continue to make these inspiring videos. Thank you, Your new devout subscriber :)
You are most welcome. Thank you for the complements 🙏 and good luck in your exam tomorrow 🤞
thank you
you’re welcome.
really helpful video! studying for the n22 exams rn
I’m glad that you found it helpful 👍 good luck
Thank you so much for this video! It really helped
🙏 you are most welcome.
Is the syllabus you use Application and Interpretation or Analysis and Approach? This was a really useful video, thank you :)
Yes it is the IB SL Applications and Interpretation syllabus. Many thanks 🙏
