    Question Tree diagram...

    Hi all,

    can you guide me how to draw the diagram in below question?

    Construct the tree diagram of the following:
    Ali has time to play roulette at most five times. At each play he wins or loses 1 point. He begins with 1 point and will stop playing before the five times if he loses all his points or if he wins 3 points that is, if he has 4 points.
    Find the number of ways the betting can occur, and find the number of times he will stop before betting five times.


    Thnx in advance.

    start with 1 point at the top of the graph (0 turns)

    the picture below is after two turns

    just keep doing that and you'll figure it out


    (-) = loss, (+) = win
