How to complete and calculate probabilities from tree diagrams where the counter (etc...) has not been replaced before the second pick.

I thank God I have found your video. . .Great explanation!! You cleared my blurry understanding and made it like crystal clear . . . Good job!

The last question was a tough question but you are a life saver thanks for your help😀

I was completely clueless about tree diagrams but now I understand it really well. Thank you so much

Hey I wanted to ask that do we have to further simply our final probability answer or just write as it is

[lamooh]

hey on the last question shouldn't u include P(BW) since you have included P(WB)? Also thank you this video helped me

Finished a probability test, wasn’t sure on how to do this, came here to make sure I was right

Now, what would happen if mrs gold selects 3 children? Would there be 3 branches then?

Hey why do we still multiply if the two events are dependant, I was under the impression we only use P(A and B) = P(A)xP(B) if it is independent events?

Hi thank u for the video very much appreciated. I’m just confused on last one. It says probability there are now more black counters than white counters so u should pick the one that makes 28/110 why the B and B one?

This really helped me a lot thanks so much!

Where are the other people in Ms Matthews’s class

On the last one why don't you include P(BW)

Hi, I like the way you explain.
I only have one question, if Sarah takes a sweet random and eats it the number of sweets goes down to 9, after that Sarah takes another sweet random without replacement, this it means that she took 2 sweets right?. If it's so why the number goes down to 9 and no to 8? and why the number of sweets goes down to one and not to 2?

You messed up on the second on he takes two socks without replacement u wrote it as if he took one

[richarddwaynemabina]

Thanks for the video
I've learned a lot 😊

[pxnthah_]

it says he take two socks at random
so why do you always take away one
