This section deals with depending events and their association, either
negative or positive. The dependent events can be classified as
-
maximally negatively associated (mutually exclusive) to;
-
negatively associated to;
-
unassociated (independent) to;
-
positively associated to;
-
maximally positively associated (inclusive).
Using Venn diagrams to represent mutually exclusive events, we see that such
events are maximally negatively associated
Similarly, when
A ⊂
B, we conclude that these sets are
maximally positively associated.
