2. A
3.C
4. A
5. A = {1, 2, 3, 4, 5, 6} is equal to 6
Step-by-step explanation:
1.A
The set A ∩ B—read “A intersection B” or “the intersection of A and B”—is defined as the set composed of all elements that belong to both A and B.
2.A
The union of A and B is the set of all those elements which belong either to A or to B or both A and B.
3.C
Those three little dots are called an ellipsis (plural: ellipses).
4.A
This is all the items which appear in set A or in set B or in both sets. We use ' (the apostrophe) to denote the complement of a set.
5. A = {1, 2, 3, 4, 5, 6} is equal to 6
The cardinality of a set is defined as the number of elements in a mathematical set. It can be finite or infinite. For example, the cardinality of the set A = {1, 2, 3, 4, 5, 6} is equal to 6 because set A has six elements.
