Question

The difference between the set of non-negative real numbers and the set of positive real numbers is:

A.an infinite set B.a null set C.a singleton set D.Null set

Answer 1

C; A singleton set

Explanation:

Mathematically, when a number is non-negative; it is either positive or zero

Now, this is because 0 identifies as neither a positive or a negative number

hence, when we find the difference between the two sets, the only number that stands out unmatched is the value 0

What this mean is that we are having a set with a single number result

So we have our answer as {0}

Which is a singleton set
