In the month of March, the weather forecast department gives the prediction of weather for the month of April. The given table shows the probabilities of forecast of different days:
| Days | Sunny | Cloudy | Partially cloudy | Rainy |
| Probability |
\(\frac{3}{5}\)
|
\(x\)
|
\(\frac{1}{10}\)
|
\(y\)
|
Based on the above information, solve the following questions:
1. The number of sunny days in April is
2. If the number of cloudy days in April is \(3\), then \(x =\)
3. The probability that the day is not rainy, is
[NOTE: Without simplication]
4. If the sum of \(x\) and \(y\) is \(\frac{4}{10}\), then the number of rainy days in April is
[NOTE: Without simplication]
5. Find the number of partially cloudy days:
