At this point YT is my teacher because I can't for the life of me understand why my biostats lectures are so complicated.

    Thank you so much, my professor brushed over this lesson, gave us the formula without explaining ANYTHING, didn’t answer any questions, and told us to drop the class if we didn’t understand.

    As someone going back to college for a geoscience degree after 10 years in business management this was SO helpful!

    14:00 He should consider x= 0 as that is also possible, which if we employ the formula, would be 0.75^30 which would be an extremely small number. It would logically make sense, usually we would have a number closer to 25% taking algebra, the chances that 0% take it from a samoke is highly unlikely BUT possible....

      You have a point.
      P(0) =~ 0.000178... in this case.
      P(1) =~ 0.00178... which is an interesting correlation.
      This is because,
      P(1) = (30 * 0.25) * 0.75^29
      P(1) = (7.5) * 0.75^29
      P(1) = (10 * 0.75) * 0.75^29
      P(1) = 10 * 0.75^1 * 0.75^29
      P(1) = 10 * 0.75^(1+29)
      P(1) = 10 * 0.75^30
      And P(0) = 0.75^30

    Firstly, thank you SO much! I have tried tutoring and have been plugging in searches throughout Google, Khan Academy, and RUclips for help with solving this type of equation (example 2). Statistics is a huge downfall for me. I want to cry a little, with relief. This video helped significantly. Oddly, this video was one of those random ones from autoplay. So, this may have been "divine intervention", which I am (again) so grateful for.

      @r.t.wickramasinghe9258 11 месяцев назад +8

      @@yarachesu2604 That is not a valid point since we do not know exact total no. of students in the high school. Say that there are 200 students in the high school XYZ. Then total no.of students taking algebra will be 50(25%). So, other 150 will not be taking algebra. So, since the 30 students are chosen randomly, there is at least a small chance that all 30 are selected from that remaining 150. So, there will be a small probability for p(0) which is actually 0.018%
