SUMMARY
The discussion centers on the correct representation of the probability of event B using a Venn diagram, given mutually exclusive and exhaustive events A1, A2, ..., An. The formula P(B) = P(A1) x P(B | A1) + P(A2) x P(B | A2) + ... + P(An) x P(B | An) is confirmed to be accurate under the condition that B is a subset of the union of the Ai events. Participants emphasize the importance of ensuring that the region outside the blue circles in the Venn diagram does not include event B, as this would invalidate the representation.
PREREQUISITES
