      Totally, 🙈. What a ridiculous mistake on my part. Soooo embarrassing.
      Thank you for the spot 👍

    Your videos are really helpful honestly. Nobody in my class took S2 except me so my teacher has little to no time to teach me about it

    in 21:38 , isn't the answer 0.9051 - 0.7384(1-p (X≤2) ) = 0.1667?

    in 30:30 shouldn't k = 14 since its closer to 0.05

    There is a question that I found online where p is 0.48 and that is not in the tables so how can i solve this one?
    Do I only get 2 options? One being that I do it manually which is time consuming if n is large or two I have to use a calculator?

    i still need to understand more about q.3 what do i have to do in terms of y

    how can i find the probability in the other calculators

      Very few calculators have the probability functions. So you would need to use the tables instead.

    IAM sitt confused about the interms of Y and how we choose the number with x can you explain that? pplease😵‍💫

      For the probability of y just subtract the probability of x from 1. For the range for example such as P(x12)
