1. The problem states the probabilities of Rosa winning two different prizes: a T-shirt with probability $0.89$ and a $20 gift certificate with probability $0.05$.
2. We want to understand which statement correctly describes the chances of Rosa winning a T-shirt or a $20 gift certificate.
3. The probability of winning a T-shirt is very high ($0.89$), meaning it is quite likely.
4. The probability of winning a $20 gift certificate is very low ($0.05$), meaning it is quite unlikely.
5. The statements are:
- A: Rosa wins both prizes (probability would be $0.89 \times 0.05 = 0.0445$, which is low).
- B: Rosa wins either prize (probability is high since $0.89$ is high).
- C: Rosa unlikely wins a T-shirt but likely wins a gift certificate (incorrect since T-shirt chance is high).
- D: Rosa unlikely wins a gift certificate but likely wins a T-shirt (matches the probabilities).
6. Therefore, the correct description is statement D.
Final answer: D. It is very unlikely that Rosa wins a gift certificate, but quite likely that she wins a T-shirt.
