I've been stuck at this for awhile now. I have problems understanding how to draw a tree diagram and how to obtain a result from the tree diagram.

O level Probability: Tree diagrams

#

each branch is a result and has a set probability

#

to get the probability of a result multiply the branch the result is on with the previous branch

#

until you get to the root

#

a set of branches is an event

#

#

for example to get 2 on the red die (first event) 5 on the first green die (second event) and 6 on the second green die (third event)

#

the probability would be 1/3 * 5/6 * 1/6
