For the events \(A\) and \(B\),
$$\mathrm { P } \left( A \cap B ^ { \prime } \right) = 0.32 , \quad \mathrm { P } \left( A ^ { \prime } \cap B \right) = 0.11 \quad \text { and } \quad \mathrm { P } ( A \cup B ) = 0.65$$
- Find \(\mathrm { P } \left( A \mid B ^ { \prime } \right)\).
- Determine whether or not \(A\) and \(B\) are independent.
