Gce Model Questions Vol1 2025 Civic Education Question 49
Practice objective / multiple choice question 49 from the 2025 Gce Model Questions Vol1 Civic Education examination.
Three peace‑building strategies—Mediation (M), Negotiation (N) and Arbitration (A)—are applied together in a conflict zone. Historical data give the following success probabilities:\n\n- Success when only M is used: \(0.50\)\n- Success when only N is used: \(0.40\)\n- Success when only A is used: \(0.30\)\n- Success when M and N are used together (at least one succeeds): \(0.80\)\n- Success when N and A are used together: \(0.68\)\n- Success when all three are used together: \(0.90\)\n\nAssuming that "success" of a combination means that at least one of the strategies in that combination succeeds, determine the probability that exactly two of the three strategies succeed when all three are employed.
