Hence your first example would be correct in a Merise diagram. – Attila Jun 19, 2015 at 9:27 Add a comment 3 Answers Sorted by: 29 WebCardinality is expressed in terms of: one to one one to many many to many Aggregation It represents a "part of" relationship. Class2 is part of Class1. Many instances (denoted by the *) of Class2 can be associated with Class1. Objects of Class1 and Class2 have separate lifetimes. The figure below shows an example of aggregation.

The cardinality of a set A is defined as its equivalence class under equinumerosity. A representative set is designated for each equivalence class. The most common choice is the initial ordinal in that class. This is usually taken as the definition of cardinal number in axiomatic set theory. See more In mathematics, the cardinality of a set is a measure of the number of elements of the set. For example, the set $${\displaystyle A=\{2,4,6\}}$$ contains 3 elements, and therefore $${\displaystyle A}$$ has a cardinality of 3. … See more While the cardinality of a finite set is just the number of its elements, extending the notion to infinite sets usually starts with defining the notion of comparison of arbitrary sets … See more If the axiom of choice holds, the law of trichotomy holds for cardinality. Thus we can make the following definitions: • Any set X with cardinality less than that of the natural numbers, or X < N , is said to be a finite set. • Any set X that has the same cardinality as … See more • If X = {a, b, c} and Y = {apples, oranges, peaches}, where a, b, and c are distinct, then X = Y because { (a, apples), (b, oranges), (c, peaches)} is a bijection between the sets X and Y. The cardinality of each of X and Y is 3. • If X ≤ Y , then there exists Z such … See more A crude sense of cardinality, an awareness that groups of things or events compare with other groups by containing more, fewer, or the same number of instances, is observed in a variety of present-day animal species, suggesting an origin millions of … See more In the above section, "cardinality" of a set was defined functionally. In other words, it was not defined as a specific object itself. However, such an object can be defined as follows. See more Our intuition gained from finite sets breaks down when dealing with infinite sets.

Now I know this is 2^n, and I remember seeing a sketch of why this was true. But the question occurred in a combinatorial context, so I thought about how to attack from a more combinatorial angle.
