As a set 1 i see people in the comments who find this harder than i do, and im the one thinking im bad at maths when it is easier for me to understand this at school then everyone else.😊

11.07 .. Sir can u explain how one number
Dropped down when 2 countes were taken

[As-iyki]

At 8:20 what if 3 counters were taken at random?
Would we have to do 3 branches?

[BrunoB]

Do you need to cancel down a probability fraction? Also, thank you for all your help.

I have heard the formula P(A AND B) = P(A) * P(B) where A and B are independent events so why are we multiplying the probabilities when the events are dependent.

Great video. Just wondering why at 11:08 rr is 3/10. however in the question it says he takes two counters out at random. Is it me or is it just the way the question is worded

[Mucha.offical]

YoU know the 2nd question shouldnt you take away 2 instead of 1 as he took 2 counters out?

[justsomeone]

thank you so much! this was quite helpful!

i feel like they need to show us your videos in school because they make so much more sense than my teacher

One doubt in the last question JACOB takes 2 sandwiches at random isn't we supposed to minus 2sandwiches from rest all in the second branches like 20/9 instead of 20/10
