Hi,
I'm little confused here.
If the range of values is 20, and the smallest number is 0,
then shouldn't the range be 0-19?
is it simply largest-smallest when we're finding the range?

Not following you. Below is the reasoning for (1)+(2):
The range of a set is the difference between the largest and smallest elements of a set: \(20=\text{largest}-\text{smallest}=\text{largest}-0\), hence \(\text{largest}=20\). Sufficient to answer NO to the question "are ALL elements of set \(S\) smaller than 20" (one element of the set, 20, is not less than 20).
Can you please tell me which part is confusing there? Thank you.
