Using Probability Tree and Graph Method to Solve the Probability of Event
Rong Wang · Journal of Tianjin Adult Higher Learning · 2004
This article presents a method to solve the probability of event named probability tree and graph method. First, draw the probability tree and graph according to the sequence of the events, then mark the probability of every event on the graph, and then go back from the end point to the start point, at last the probability can be solved by using the multiplication formula and the addible attribute of the probability.
