Which of the following is NOT included in the set of numbering systems shown?

Explanation:
Numbering bases are defined by how many digits they use and how place values grow. The set shown includes binary (base 2), decimal (base 10), and hexadecimal (base 16), which are commonly used in computing. Binary uses digits 0 and 1, decimal uses 0 through 9, and hexadecimal uses 0–9 plus A–F to cover values 0–15. Base 5, which would use digits 0–4 and powers of 5, isn’t part of those bases. So the numbering system not included is base 5.
