Question

this kind of precision only applies to measurement counting numbers (1,2,3...) defined values (1 dozen = exactly 12) (1 km = exactly 1,000 m) the above values have infinite precision what type(s) of numbers have infinite precision? defined values only (like 1 dozen = 1 exactly 12) counting numbers only neither of these both of these

Explanation:

Counting numbers (1, 2, 3, ...) and defined values (like 1 dozen = 12, 1 km = 1000 m) have infinite precision because they are exact and not subject to measurement error. So both types of numbers have infinite precision.

Answer:

Both of these
