Question

Which of the following statement is TRUE. Select one: a. Non-countable values are called discrete variables b. Infinite numbers are considered discrete variables. c. Countable number of values are called discrete variables d. All of the statements are TRUE.

Answer 1

Answer: The answer is (c) Countable number of values are called discrete.

Step-by-step explanation: We know the meaning of the word "discrete" in mathematics.

In terms of variables, distinct and countable variables are termed as discrete. And, non - countable and infinite numbers are not termed as discrete.

For example, [2,3] contains all the real numbers between 2 and 3, so we cannot write them distinctly and hence they are not discrete. On the other hand, the numbers in the set {1, 2, 3, . . .} are distinct and countable, and hence they are discrete.

Thus, the correct option is (c).
