Which of the following sets is not finite?
a. {x|x is a natural number less than 10}
b. {x|x is a whole number between 0 and 10}
c. {x|x is an integer that is less than 0}

Respuesta :

It's C, because there are infinitely many integers less than 0: [tex]-1,-2,-3,-4,-5,\ldots[/tex] etc.
I got this question wrong, so when I went over my answers later I found out the correct answer is

A. {x|x is a natural number less than 10}
