Which of the following is not a property of a measure (\mu) on a set (X): (\mu(\emptyset) = 0), (\mu(A \cup B) = \mu(A) + \mu(B)) for disjoint sets (A) and (B), or (\mu(A) \leq \mu(B)) whenever (A \subseteq B)?
Let (\mu) be a measure on a set (X). If (A_1, A_2, \ldots) is a sequence of sets in (X) such that (A_n \subseteq A_{n+1}) for all (n), then what is the limit of (\mu(A_n)) as (n) approaches infinity?
Which of the following is not a type of measure: Lebesgue measure, counting measure, or probability measure?
Let (\mu) be a measure on a set (X). If (A) and (B) are sets in (X) such that (A \cap B = \emptyset), then what is the relationship between (\mu(A \cup B)) and (\mu(A) + \mu(B))?
Let (\mu) be a measure on a set (X). If (A_1, A_2, \ldots) is a sequence of sets in (X) such that (A_n \cap A_m = \emptyset) for all (n \neq m), then what is the relationship between (\mu(\cup_{n=1}^\infty A_n)) and (\sum_{n=1}^\infty \mu(A_n))?

Let (\mu) be a measure on a set (X). If (A) is a set in (X) such that (\mu(A) = 0), then what is the relationship between (\mu(A \cup B)) and (\mu(B)) for any set (B) in (X)?
Let (\mu) be a measure on a set (X). If (A_1, A_2, \ldots) is a sequence of sets in (X) such that (A_n \downarrow A) (i.e., (A_1 \supseteq A_2 \supseteq \cdots) and (\cap_{n=1}^\infty A_n = A)), then what is the relationship between (\mu(A_n)) and (\mu(A))?
Let (\mu) be a measure on a set (X). If (A_1, A_2, \ldots) is a sequence of sets in (X) such that (A_n \uparrow A) (i.e., (A_1 \subseteq A_2 \subseteq \cdots) and (\cup_{n=1}^\infty A_n = A)), then what is the relationship between (\mu(A_n)) and (\mu(A))?
Let (\mu) be a measure on a set (X). If (A) and (B) are sets in (X) such that (\mu(A) = \mu(B)), then what is the relationship between (\mu(A \cup B)) and (\mu(A \cap B))?
Let (\mu) be a measure on a set (X). If (A) is a set in (X) such that (\mu(A) = 1), then what is the relationship between (\mu(A \cap B)) and (\mu(B)) for any set (B) in (X)?

Let (\mu) be a measure on a set (X). If (A_1, A_2, \ldots) is a sequence of sets in (X) such that (\mu(A_n) \to 0) as (n) approaches infinity, then what is the relationship between (\mu(\cup_{n=1}^\infty A_n)) and (0)?
