4 For a group of 250 cars the numbers, classified by colour and country of manufacture, are shown in the table.
| Germany | Japan | Korea |
| Silver | 40 | 26 | 34 |
| White | 32 | 22 | 26 |
| Red | 28 | 12 | 30 |
One car is selected at random from this group. Find the probability that the selected car is
- a red or silver car manufactured in Korea,
- not manufactured in Japan.
\(X\) is the event that the selected car is white. \(Y\) is the event that the selected car is manufactured in Germany. - By using appropriate probabilities, determine whether events \(X\) and \(Y\) are independent.
