how do you use a tree diagram to determine the probability of an event? provide an example.

if you are using a tree diagram for a coin you will need to write H and T and if you try to get 2 heads in a row in 3 flips. it would look like my picture

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
