우주가 아닌 다른 세계관이 있다.
이 세상 사람들은 전투를 워낙 좋아한다
이 세상에는 5개의 나라가 있는데 이름이 각각 x,y,z,a,b이다.
x나라의 면적은 100000이고 y나라의 면적은 90000이다
이어서 z는 80000이고 a는 70000이고 b는 60000이다
이 나라 사람들은 폭탄을 많이 가지고 있다
폭탄은 3종류가 있다
1. 핵보다 강한 폭탄: 10000만큼의 면적을 없에버릴수 있다
2. 핵폭탄: 6500만큼의 면적을 없에버릴수 있다
3. 일반폭탄: 5000만큼의 면적을 없에버릴수 있다
x: 1번 폭탄 0개, 2번 폭탄 20개, 3번 폭탄 20개
y: 1번 폭탄 5개, 2번 폭탄 13개, 3번 폭탄 15개
z: 1번 폭탄 7개, 2번 폭탄 10개, 3번 폭탄 10개
a: 1번 폭탄 10개, 2번폭탄 0개 3번 폭탄 10개
b: 1번 폭탄 15개, 2번 폭탄 5개, 3번 폭탄 0개
x나라부터 원하는 나라한테 폭탄을 1개씩 던질때, z나라가 이 전쟁에서 2등할 확률은?
