27:19 You can also the Inverse Binomial function in Statistics mode to solve this questions. However, be careful, as like I show in Distribution mode at 30:06, the values given are those with the probability closest to 2.5% not the first value with a probability less than 2.5% as required
Much better doing the last part of the last question entirely in the RUN/MAT mode of the fx-CG50, as opposed to first using the statistics mode. Press the OPTN button and select CALC followed by SolvN. Next, press F6 followed by F3(PROB). Press F6 again and select P(. Now press the fraction key and, in the top box, enter 180-160. Go to the lower box and enter x. Get the cursor to the right of this fraction and select the = shown in yellow (SHIFT decimal point). To the right of the = sign, enter 0.8, and then press EXE, followed by EXIT. The calculator displays 23.763659, giving you the answer directly. Remember that on Casio calculators (even the inferior fx-991ES) P( is the command for P(Zz). Both can be used with SolveN or Solve commands on the Casio graphics calculators, though I don't think you can concatenate with P( or P( on an fx-991ES!
I’ll try, but my main focus will be on the Edexcel Alevel as that’s what I teach at my school. There is a lot of cross over content, hopefully that will be useful for you.
Thank you for this video 🙏🏽 I was wondering if you could reupload the As Stats n mechanics paper 2022 video or send a link, I was mid watching the paper last night and the video seems to have disappeared

I don’t have a distribution button on my fx-cg50
Thanks you're the best, just finished my paper 3 today. Was absolutely terrible, but hopefully my pure will make up for that.
Legend thank you!
is CG-50 allowed is P1, P2, P3 & P4?
I use the graphical calc. What extra working do I need to show?
sir ive watched you since 1k subs truly the goat

I’ll try, but my main focus will be on the Edexcel Alevel as that’s what I teach at my school. There is a lot of cross over content, hopefully that will be useful for you.
