수학동아 - 폴리매스
함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.
[문장제 문제&개념응용] 마피아 게임-초급(난이도 ◇●)
일단 마피아 게임은 다들 아시는데,이 마피아 게임에서 역할들의 의미는 상당히 중요합니다. 역할이 잘함에 따라 심리적으로 사람들의 칭찬과 비난을 받을 수 있는 것들이기 때문이죠.
그러면 이제 가장 기초적인 마피아 게임을 시작하겠습니다.
1. 마피아만 정하고 하는 마피아 게임에 25명이 참여할 때,마피아의 수를 a명이라고 하자. 마피아가 15명을 죽게 하면 승리할 때,수학적으로 a가 몇이어야 공평한 게임이 되는가?
(우리가 아는 흔한 정치질의 경우의 수 제외)
2. 마피아가 누군가를 죽이기만 하면,투표하는 것만으로 마피아를 죽여야 하니,정치인을 넣자(투표로 안죽음). 정치인이 있을 때,마피아는 그대로여도 승률의 변화가 적은가,또는 승률에 큰 영향을 주는가?
공평한 게임의 원칙: 승률이 45~55% 사이로 나타나게 하라!(정확히 50%로 맞추지도 못할 듯합니다.)

초급부터 세바문에 넣을 정도로 난이도를 두면 안되니까,여기 둡니다. 열심히 푸세요,그라고 이거 풀고 원래 문제도 풀어주세요!

1명이면 밤에 1명 죽이고,여러 명이면 논의해서 1명 죽이겠죠?
