Need a reminder? The key ideaShow
An experiment has outcomes you cannot know in advance. An event is a set of outcomes; its favourable outcomes make it happen. Outcomes are equally likely only when none has a better chance than another, as with a fair die or equal sectors.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
