Final answer:
The set of students who are either taking Calculus I or in the Computer Science major at ODU can be represented by the union of sets X and Y.
Step-by-step explanation:
The set of students who are either taking Calculus I or in the Computer Science major at ODU can be represented by the union of sets X and Y, denoted as X ∪ Y.
X represents the set of students in the Computer Science major at ODU, and Y represents the set of students taking Calculus I at ODU.
The union of two sets includes all the elements that belong to either set. In this case, it includes both the students in the Computer Science major and the students taking Calculus I.
For example, if there are 100 students in the Computer Science major and 150 students taking Calculus I, the set X ∪ Y would contain a total of 250 students.
