Hello, so we have a question right here that says, how would you determine the multiplicity at the end of an association representing a relation between instances of three classes? so to determine the multiplicity at the end of an association, representing a relation between the instances of three classes, you would need to consider the cardinality of the relationship between each pair of classes.

So we have in um.
00:30
L, the multiplicity describes the number of instances of one class that can be related to the instances of another class through an association.
00:40
So multiplicity can be expressed using a range such as 0 to 1, 1, 4, or 2 to 4, where the first number represents the minimum of the instances, and the second number represents the maximum number represents the maximum number.
01:02
Of instances.
01:04
Okay, so if there are three classes involved in the association, you need to consider the multiplicity at the end of the association for each pair of classes.
01:15
For example, if you have the classes a, b, and c, a is related to b, b is related to c, you need to consider the multiplicity at the end of the association between a and b and the multiplicity at the end of the association between b and c.
01:39
Okay, so the multiplicity at the end of the association between a and b will affect the multiplicity at the end of the association between b and c...
