One man has to pass a legislation test that involves deciding which Legislation was met and which legislation was not met based on 8 pieces of evidence assessed by 9 Quality assessors, 8 of whom have a different interpretation of the evidence to the man. This is a pass or fail scenario. What chance of passing does this person really have? Please show me in diagram form with an answer. It is a random selection who marks the test.
