    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)

    In part c , how did you know the v is going to be on the positive side of the graph and not the negative

    • @yaseralshroofi
      @yaseralshroofi 6 місяців тому +2

      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

    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.

      @@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)
