A computing course offers four different programming languages: Java, Python, Kotlin, and TypeScript. A random sample of 200 learners was selected from the recent enrollment data, and it was found that 35% of them opted for Java, 14% for Python, 27% for Kotlin, and the rest selected TypeScript. Fifty students who opted for Java and 50% of those taking Kotlin are using Windows laptops; a quarter of those who opted for Python and 25% of those taking Typescript are using Macbooks.
