Order the reasoning: from a partition to a posterior

Read exercise and reference answers
Steps
  1. The sample space is split into disjoint causes
  2. Each cause carries a prior probability
  3. Each cause makes the observation more or less likely
  4. Adding the branches gives the overall chance of the observation
  5. One branch divided by that total is the revised chance of that cause
This is Bayes' theorem told as a sequence rather than a formula. Source: syllabus Maths Part II, Ch 13 Probability.
