The best verbal descriptions for the probabilities are:
- For \(0.04\): The event is unlikely to occur.
- For \(0.88\): The event is likely to occur.
Thus, the answers are:
- For part (a): The event is unlikely to occur.
- For part (b): The event is likely to occur.
\(\boxed{\text{Part (a): unlikely, Part (b): likely}}\)
