Your stats videos are so incredibly helpful! I have a year 1 stats test tomorrow and you have genuinely saved me from having a terrible grade, thank you! 🙏I would love to see you continue to do a level maths revision videos in the near future :)
this video and the chapter 7 videos are amazing. wish they would have just used this video to teach us as it makes it so much simpler to understand and goes through why you do something and not just the steps to do it. thanks again for this quality content
So the 1/5 is the probability of a success from the B(n,p) part and the X = 3 you can always assume by default as being having "3 successes" (usually the question will make it explicit, but if it does not, assume its a success). Hope that clarifies it!
Hey sorry for the late reply, so here it should be as in the video ! If you have the text book, its the same as the example on page 93. Take a look at that example, its pretty much the same - if that example doesn't make sense though, let me know here and I'll be glad to explain each of the steps as to why we got what we got!
Yeah a few people spotted this, the right way to do it is basically 1 minus everything else - silly mistake there by me (or for the other approach check my reply to "Yes, I Like Bannans, so ?" above. Hope it helps ^^
@@SachchitP hi i wanted to ask will you upload any new videos anytime soon :) your videos are soo helpful and many of my friends have watched them too we appreciate the explanations you do thank you 😊

21:53 why can't the 5th spin give a green? all five possibilities must add up to one.
It seems he made a mistake there, how you figure it out is 5 reds add 4 reds and a green
yep he didnt account for this possibility which is required for the sum of the probabilities to be 1
This guy is a don. RESPECT
Have been self teaching stats for A level and your videos have been brilliant, thank you! If you ever fancy doing year 2 let me know :)
Thank you brooo u saved my statistics exam ur a legend
I've got my mock in 3 days and this was super helpful. Thanks so much! :)
These videos are so helpful! Thank you so much :)
thank you so much for making this video!!!
you're SO helpful !!!!!!! thank you so much, you should most definitely make videos on pure AS maths too
Life saviour 🙏
You explain so well thankyou 🖤
i have stats exam for a levels on tuesday, thankyou very much for this
this is so helpful
Please can you do normal distribution next
thank you! you really saved me for my year 12 mocks!
Which button on the calc helps with cumulative probability
Thanks alotttttttttttt❤
can you do a mechanics version please
very helpful :) thank you, it would be great if u can do videos on chapter 7 normal distribution :")
27:24 does that mean the probability is always gonna be a success because it doesn’t say in the question whether p(x=3) is a failure or a succes
So the 1/5 is the probability of a success from the B(n,p) part and the X = 3 you can always assume by default as being having "3 successes" (usually the question will make it explicit, but if it does not, assume its a success). Hope that clarifies it!
Hi this video is really helpful but at 42:48 wouldn't it be 1-P(X

thank you so much.
wait what do you press on the calculator?? for binomial distributions??
set up, 7, and then either 4 or 5

is the answer to the last question 7
you do the spinner question wrong
