Question

c. which of the following describes the set of whole numbers greater than or equal to 155? a. it is not well defined. it is not possible to list all of the whole numbers greater than or equal to 155 b. it is well defined. it is possible to list all of the whole numbers greater than or equal to 155 c. it is well defined. given a number, it is possible to tell whether it is a whole number greater than or equal to 155 d. it is well defined. given a number, it is possible to tell whether it is a whole number e. it is not well defined. there is no clear meaning of whole numbers f. it is not well defined. there is no clear meaning of greater than or equal to 155

Explanation:

A well - defined set has a clear rule to determine membership. For the set of whole numbers ≥155, given a number, we can check if it's a whole number and ≥155 (clear rule). Option A is wrong (we can define the set even if infinite). Option B is wrong (we don't need to list all, just have a rule). Options D - F are wrong as the set is well - defined. So option C is correct.

Answer:

C. It is well defined. Given a number, it is possible to tell whether it is a whole number greater than or equal to 155
