Conditional ones will not appear on the foundation paper. You need to check the language carefully to determine if the probabilities change. Another thing is where it comes in the paper. If it is early on it will likely be dependent, later on will almost certainly be conditional.
Great video if you approach the sums using a tree diagram . However , could Bayes' theorem be used in the same examples, its hard to know when to use the formula or using a tree diagram ?
literally telling everyone abt this channel
Excellent. Thx
No worries!
How we know the difference between conditional probability and the tree diagram(dependent probability)questions??

honestly you guys are the best i've never been ale to do these type of questions, I'm so grateful, thank you!!
Thanks! Although theres not guys, its just me on my own!
@@1stClassMaths ur a great math teacher im stressing and also im doing foundation so i wont get harder questions like the ones in the video?
helps a lot thanks, do you have a video on vectors?
Not yet but its on my list to do.
thanks. Your website is very useful as are your videos. saving my gcse's.@@1stClassMaths
when it is 12:19 how do you take away 1-24/6840. On my calc i keep on getting weird decimals
If you got 0.9964912281 then this is also acceptable.
@@1stClassMaths man u guys deserve a sub

Hi. You are effectively using the theorem when calculating the probabilities but we do not teach the theorem really until A-Level.

Hi. on ur paper 2 topics, it states ‘successive events’ probability, is this it?
This is an example yes

Why it is not the probability that represents randomly selecting 2 sweets of the same flavor without caring any information?
