Which of the following examples represents a discrete data constraint with viable solutions
1) Counting the number of students in a classroom - This represents discrete data as the number of students can only take on whole number values. Viable solutions can include any whole number value from 0 onwards. For example, there could be 25 students, 0 students, or 100 students in the classroom.
2) Recording the number of cars passing by a traffic camera within a given time period - This also represents discrete data as the number of cars can only be a whole number. Viable solutions can include any positive whole number value. For example, there could be 10 cars, 0 cars, or 100 cars passing by the traffic camera.
3) Tracking the number of books sold at a bookstore in a month - Again, this represents discrete data as the number of books sold can only be a whole number. Viable solutions can include any positive whole number value, starting from 0. For example, there could be 50 books sold, 0 books sold, or 200 books sold in a month.
In all these examples, discrete data is used, and there are viable solutions that can be expressed using whole numbers.
