스페이스는 1학년 애들한테 실험을 한 번 해보려고 한다
실험은 다음과 같다
1. 두 사람이 짝을 지어 가위바위보를 해서 이긴 사람이 먼저 초콜릿 금화 100개를 갖는다
2. 그 중 일부를 진 사람에게 주거나 주지 않는다
3. 정 20면체 주사위를 5번 굴리고 5번 굴린 것의 합을 구한다
3-1. 만약 5가 나왔는데 하나도 안 줬으면 1개만 빼고 다 잃는다(주면 그대로다)
3-2. 만약 6~10이 나오면 남은 값의 반만 잃는다
3-3. 11~20이 나오면 그대로다
3-4. 21~35가 나오면 1/2만 받는다
3-5. 36~65가 나오면 준 만큼 받는다
3-6. 66~80이 나오면 2배로 받는다(77 제외)
3-7. 81~85가 나오면 3배로 받는다
3-8. 86~90이 나오면 5배로 받는다
3-9. 91~95가 나오면 10배로 받는다
3-10. 96, 97이 나오면 20배로 받는다
3-11. 98이 나오면 30배로 받는다
3-12. 99가 나오면 50배로 받고 100개를 얻는다
3-13. 100이 나오면 100배로 받고 200개를 얻는다
3-14. 77이 나올 경우 777배로 받는다
3-15. 순서에 상관없이 7이 나올 때 마다 7개를 얻는다
(만약 정수가 아닐 경우 반올림한다)
그럼 더 많이 갖고 있을 확률이 높은 사람은 누구인가?
