Frequency Tree Diagram Concept Extended to Probability with Application Example

Tree diagram is an effective way to represent sequence of events. We will first learn how to read and understand the given information and then create a tree diagram with all possible number values. These values represent outcome at each stage and are very helpful to calculate probability of events. We will then extend the question to find probability of events.
Example:
320 acts took place in a talent show.
40% of the acts danced. The rest sang.
27 of the acts to qualify for the next round were from the singing group.
75 of the acts from the dance group were sent back for training.
