Hi - I found this video on tree diagram.
Watch it over the weekend and answer question 6 on page 168 (textbook). Draw a tree diagram to answer this question. Bring the work to school when term re-opens on 17 March. If you have any questions, pls post them as comments and I will try to answer them.

wahahaaaaaa.im 1st i understand the video okok but not the last part,the find the G thing.
maybe the person should try to present his speech into more words.
because sometimes he speaks quite unclear. hahah. but ya, i understand [:
Ok...I tink I understand a little bit more about probability liao!But I still dun understand why when they ask for only at least 1 G,need also include the 2Gs..I thought is only got 1 G in it then count rite?
P(At least one G) means as long as you have 1 green ball, then it counts. So GG satisfies the question.
If I change the question to P(only one G), then the GG is not counted.
Yours sincerely,
