수학동아 - 폴리매스
함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.
[문장제 문제&개념응용] [필즈상]수학자들의 조합대결3-번외편
10명의 수학자들은 서로 대결을 하다보니 서로가 정말 스마트한 사람이라는 것을 알게 되었다.
그래서 10명의 수학자들은 다 함께 모여 공동 연구를 하기로 했다. 연구 주제는 10명의 연구 주제를 모두 다 합친 정수보형대수기하조합미분기하위상프록그램통역학계수리물리확률산술기하학(...)
여튼 함께 연구를 하기로 했는데 그래도 계속 연구만 하면 힘드니까 서로 번갈아가면서 연구를 하고 ㅁ쳐명은 자고 이런식으로 하기로 했다.
(연구 분야가 걍 다 짬뽕한거라서 별 상관 없음)
하지만 연구는 조금이라도 해야하니까 최소한 한명 이상은 깨어있어야 한다.
이때 수학자들이 수학자들의 연구하는(자거나 꺠어있거나) 경우의 수를 구하시오
copyright.polymath(?)
이런 문제를 참경과 수세라는 두 사람이 각각 풀었다.
참경의 풀이
전체 경우의 수: 2^10, 모두 자는 경우의 수: 1
--> 구하는 답: (전체)-(모두 자는 경우의수): 2^10-1
수세의 풀이
한명을 고정으로 연구하게 하고 나머지는 알아서 한다.
10*2^9
이 중 맞는 풀이를 고르고 이유를 서술하시오.
