      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

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❤️❤️❤️❤️

    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.
