Neco 2020 Civic Education Question 6
Practice objective / multiple choice question 6 from the 2020 Neco Civic Education examination.
In a community there are five conflicting parties P1, P2, P3, P4 and P5. A mediator can conduct a mediation session with at most three parties at a time. In each session every pair of parties present discusses their issues, so a session with three parties resolves the three distinct pairwise conflicts among them. The peace committee wants to ensure that every possible pair of parties (there are \(\binom{5}{2}=10\) pairs) meets in at least one session. What is the minimum number of distinct mediation sessions (and therefore mediators) required to achieve this?
