Question 4 Image Processing

Imagine that there are four things that you like to do in the evening: going to a pub, watching TV, going to a party, or studying (!). The choice is sometimes made for you-if you have an assignment due the next day, you need to study, if you're feeling lazy then the pub isn't for you, and if there isn't a party then you can't go to it. You are looking for a decision tree which will help you decide what to do each evening. Here is a list of everything you've done in the past 10 days.
