The number of computers in a library.
 A discrete data B continuous data C Either A or B D None of the above
Explanation:

Detailed explanation-1: -A computer is a finite state machine that may be viewed as a discrete system. Because computers are often used to model not only other discrete systems but continuous systems as well, methods have been developed to represent real-world continuous systems as discrete systems.

Detailed explanation-2: -The number of books in a library is a discrete type random variable, because it is finite and its value can be obtained by just counting.

Detailed explanation-3: -Items are counted in discrete units – one unit, two units, three units, etc. For example, the number of correct answers on a 25 question test could be one of 26 values ranging from zero to 25.

Detailed explanation-4: -Discrete data is a type of quantitative data that includes nondivisible figures and statistics you can count. You typically write discrete data points as numbers that represent exact values. You can often describe discrete data by using the phrase “the number of, ” such as the number of customers in a store.
