    Hey i had a question. On question 6)c), you chose from the identicals, as in,
    "3c1 to choose one O from 3 O's
    But in other question where the word was "crocodile" and the question was similar, they didn't choose from the identicals. like there were 2 O in crocodile, but they didnt take "2c1".
    So can you please please please explain why is there this disparity?
    The question was from 9709/MJ/22/52

      with this one the word random changes everything

      Because this one is ‘probability’ and that one was ‘possibility’

      I'm confused about this too. When there's probability we'll separately select each repeating letter? And when there's only number of ways we'll use just the remaining letters

      @@fatimahmunawar5030 Basically When the question asks for a probability, you are gonna Treat every option as an individual option. Even if they are the same. For example, in ALLIGATOR, There is 2 Ls but we are gonna treat it as an independent choice.
      Whereas if the question asks for anything other than probability, then we will consider it Identical. Hope that clears it out.

    I'm confused about this in the combination questions. When there's probability we'll separately select each repeating letter? And when there's only number of ways we'll use just the remaining letters?

      THIS^^^^ im so confused about this because in other questions they don't select each repeating letter

    You missed a step in question 6 part c at 43:19. The Answer would be divided by 8C4 as it question is of probability

    Hi, thank you so much for your work. I really appreciate this. Just in question 4(b) you have a little mistake it should be 32/9 not 34/9

      Thank you so much for pointing out the error!

  • @Nohandleyetf
    @Nohandleyetf Год назад +2

    for question 6, it asked for the probability not for the number of possibilities

    • @studywithprashna
      @studywithprashna  Год назад +2

      Right, I seem to have listed all the possibilities but not the final probability.
      Thank you for pointing it out!

    Which school did you go to for A Levels?

    heyy pls reply quick . so in Q 1 b part why dont we add the failures too. the 1st second and third failues

    • @studywithprashna
      @studywithprashna  Год назад +2

      Because the question states that the first 5 is obtained AFTER the third row, so we do not need to consider first, second and third failure.

    search how to pronounce probability 😂

      If it bothers you so much you can just not watch the video, you know? No need to comment the same thing on every video. If you're here to learn, focus on understanding the concept rather than focusing on how annoying you find the way I pronounce probability.
