1. If \(U = \{x : x \in \mathbb{Z}\) and \(-3 \le x \le 5\}\), \(A = \{-1\), \(2\), \(3\), \(4\}\) and \(B\) \(= \{-2\), \(1\), \(3\), \(5\}\), then \(n(A^{\prime}) = 3\).
 
The given statement is .
 
 
2. If \(A\) and \(B\) are two finite sets, then \(n(A \cup B) = n(A) + n(B) + n(A \cap B)\).
  
The given statement is.
 
 
3. \(n(A^{\prime}) = n(U) - n(A)\).
 
The given statement is.
