I am really confused with expressing different types of events using probability trees and venn diagrams.
Is it possible to represent dependent events using a venn diagram? I know it can be shown using a tree diagram because you can work out the $P(A|B)$ but surely this can't be represented using a venn diagram?? Or do you have to work out the probability yourself because does the venn diagram show the actual probability or only the frequency of events?
And can you represent not mutually exclusive events using a tree digram? Or is this only possible for venn diagrams because there's no intersection area in the tree diagram.
Much appreciated if someone can explain.
