Good day Sir. Thank you for all you do. Your channel have been of immense help to me various ways, more help than my school lecturers ever were. Thanks so much, may God multiply the blessings in your blessed life on my behalf, Amen. Please Sir, I need your clarification on question 2 B 12:18 . To me, you are a demi maths god but I beg to disagree with you on it. In my thought, it's either you want to test if we are paying detailed attention to the formula or you got it wrong. From what I have learnt from you and what I know in probability, the solution should be as follows: P(Br|M) = 70/90 = 7/9 Or P(Br|M) = P(M and Br)/P(M) =(70/200)/(90/200) = 70/90 = 7/9 = 0.7778 = 77.78%. Please correct and clarify me if I am wrong. Please tag me when you do. Thanks
Dude, your videos are always so clear and to the point. You're a godsend. Crazy how it doesn't even require any fancy animations or anything, just clear examples and explanations. You are a fantastic teacher!
now, 21/8/2024, I'm about to have mid term exam tmrw, binge watch every damn clip about probability and statistic like you did, may the force be with me >:D
Omg THANK YOU SO MUCH FOR THIS LESSON. I literally sat in my math class for an hour and 40 min straight and I can't understand anything that my teacher is saying. Literally your video is less than 20 min and I understood right away!
Me spending math online class for 2 periods 😶 vs me spending math class with this guy 😲. . . . . . . . . . . . . . . THANK YOU FOR MAKING MY LIFE EASIER!!! I DON'T UNDERSTAND ANYTHING THAT I LEARNT DURING ONLINE CLASSES 😭
Not everything is fine for me it's because other mathematic topics suit my ability. Those my friends are nice people they the other ones don't go to my college like Zachary his classmates probably now go to any type out there.
Thank you thank you thank you! Even after watching my lecture videos and reading my textbook, I was still so confused. This saved my life. You're a godsend!
I don't know why I pay tuition fees for my university faculty. If i don't understand anything at the end of the day, i have to come to this RU-vid channel and make a solution. And things are very easy to understand. If The Organic Chemistry Tutor had been my university faculty, I probably wouldn't have had to struggle so much. May Allah grant you long life❤️❤️❤️❤️
Thank you very much for your video. Now I clearly understood conditional probability with Venn diagram amd Contingency table. Once again I am so glad and thank you very much
Your videos helped me so much! Thank you for clarifying and making it easy to understand. Your videos helped me understand chemistry a lot better too lol thanks again! 🤓
Circle A=150 total. Here circle A contains 150+30=180. Start with the shared portion(intersection of A and B), then subtract that from the 150 & 180.... but I could be wrong. I came here to learn from the master.
I agree--the discrepancy really threw me off. Wording of the question should change, if 150 is not TOTAL number of students taking Algebra, but 150 taking ONLY Algebra. Weird that I'm writing this 2 years later.
OMG BETTER THAN MY MATH TEACHER. SHE HAD NO IDEA HOW TO EXPLAIN THE FORMULA AND OUR TEST IS TOMORROW, AND YOU LITERALLY JUST SAVED MY REPORT CARD.. TYSM!!!
I saw this on a friend's status, i immediately came to download it and I've been listening for more than a month now and everytime i listen, i get goosebumps. This is wonderful. God bless you for such a wonderful ministration
Thank you soo much, truly u have made it very clear for me, bkoz your explanations are exactly Wat I needed to hear thank you so much sir.... May God bless you 💚💓💚
Thank you so much! I'm not that good in math but I understood your explanation than my own teacher. The video is great and easy to understand! 😍 SUBSCRIBED
At 5 min, The question says 150, but on your vann diagram we now have 180 students taking algebra, Please explain further. Isn't suppose to be 120 and 30, vs 150 and 30?
No, he wrote down P(A) and. P(B) down without subtracting P(A n B) as is typically done. So... he didn’t have to subtract and then add it back in later.
I love your explanations and ypur channel. But I think in the 1st example you should from 150 substract 30, because these 150 include All students that have Algebra and they also may have Chemistry. and 150-30 it will be 120 students that take Only Algebra. What do you think about it?
The picture isn't drawn quite clear, it'd probably better to put numbers like 120/30/50 i.e. labelling the mutually disjoint parts, I believe it's more intuitive and established notation if we put numbers on Euler-Venn diagrams. However "the student is taking Algebra" should not be interpreted the exclusive "Only Algebra" so that calculation is correct, whereas if we question the probability of Only Algebra => it will be 120/500 for sure.
This is a fantastic explanation! So can we think of conditional probability as 'changing' the sample space to a new base? For example if we have a 'given it has brown eyes' the new sample space is the column Br and we have to compute any other conditional probability by referring back to this sample space instead of the global sample space.
For the probability of students taking Algebra, is it only 150? Can it be 150+30, since the 30 students are also taking Algebra? I'm a bit confused because the question is about students taking algebra and not "Algebra ONLY". I hope you can answer my question. I'M A FAN! God bless.
I was also confused by that, but I think he made a mistake; the algebra column should be 120, and the chemistry column should be 50 (I basically took away 30 from the initial amount). The intersection would remain 30. The answers makes more sense if the Venn diagram was filled with these numbers.
B) why is the divisor 200 when we are only considering male with brown eyes? compared to C) where you only considered having 170 of the female that it has brown eyes? should that not be 200 as well like you did in P(M & Br)?
