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.
