BONUS QUESTION

Give the definition for the following vocabulary or symbol, best description for both wins: 

1. True value: The true value of a measurement is the value that would be obtained by a perfect measurement. It is the most accurate measurement. 

2. ∅: The empy set. This is a set with no elements so n(∅) = 0. The empty set is a subset of any set.
