SUMMARY
The discussion focuses on calculating the conditional probability P(A' n B' | A') using the known probabilities P(A), P(B), and P(A n B). The formula derived is P(A' n B' | A') = [1 - P(A u B)] / [1 - P(A)], which simplifies the computation of the probability of the complements of events A and B given A. The participants confirm the correctness of this formula, emphasizing its utility in probability theory.
