What does a Venn diagram consist of?
AA grid of rows and columns holding joint counts
BA box for the sample space with circles for events
CA set of branches labelled with each probability
DA curve rising from zero up to a total of one
Answer & Solution
Correct answer: B. A box for the sample space with circles for events
1. The outer box stands for the sample space, the universe of everything that can happen.
2. Circles or ovals inside it stand for the events.
3. Where two circles overlap is the intersection, and everything they cover between them is the union.
