Read about our approach to external linking. Two events are independent if the probability of the first event happening has no impact on the probability of the second event happening. This is the currently selected item. Here we see the factor tree of 48 which reveals that 48 = 2 × 2 × 2 × 2 × 3 Event tree analysis (ETA) is a forward, top-down, logical modeling technique for both success and failure that explores responses through a single initiating event and lays a path for assessing probabilities of the outcomes and overall system analysis. Constructing probability tree diagram is one of the ways that helps us solve probability problems. by . Tree diagrams are a helpful tool for calculating probabilities when there are several independent events involved. That was a simple example using independent events (each toss of a coin is independent of the previous toss), but tree diagrams are really wonderful for figuring out dependent events (where an event depends on what happens in the previous event) like this example: You are off to soccer, and love being the Goalkeeper, but that depends who is the Coach today: Sam is Coach more often ... about 6 out of every 10 games (a probability of 0.6). With replacement When replacing, the probabilities do not change. Figuring out probabilities in math can be confusing, especially since there are many rules and procedures involved. 1.
