7. Find the correct answer

If \(U = \{y: y \in \mathbb{Z}\), \(-1\le y \le 10\}\), \(A = \{y: y = 2a + 1\), \(a \in \mathbb{Z}\), \(-1 \le a \le 4\}\) and \(B = \{y: y = 3a + 1\), \(a \in \mathbb{Z}\), \(0 \le a \le 3\}\), then find the following:

 

(i) \(A^{\prime}\) \(=\) \(\{\)\(\}\)

 

(ii) \(B^{\prime}\) \(=\) \(\{\)\(\}\)

 

(iii) \(A^{\prime} \cap B^{\prime}\) \(=\) \(\{\)\(\}\)
