3.3.1 Exam Question Type 1

As far as a probability tree itself is concerned, there is not many different ways question can be asked. The only way it can be asked is either by giving you a tree and asking you to complete it and use it to answer questions. Or another way to ask is to give you some descriptions and let you draw a tree to answer questions.

All the possible variations come from the probability basics that we discussed in ‘3.1 From Description’.
