제발 풀어주셨으면 좋겠다만..
풀리려나 모르겠네요
(단순문제라서 안 풀릴듯)
어떤 loddo게임에서는 랜덤한 확률로 돈을 지급해준다.
버튼은 총 네 개가 있다. (참가, 상금, 확률, 받기)
상금 룰렛은 5000,7000,10000이 적혀있고, 확률 룰렛은 25%,50%,75%가 적혀있다.
참가 버튼을 한 번 누르면 돈 1000원을 지불한다.
그리고 룰렛을 돌아가는데 받을 확률을 먼저 알려준다.
받을 확률을 보고 포기하면 2000원을 얻고 상금버튼을 누르면 상금이 공개된다.
상금을 보고 포기하면 돈을 얻을 수 없다.
그리고 받기 버튼을 눌렀을 때 확률에 따라 상금을 얻는다.
그리고sigma는 돈 3000원을 가지고 있다.
5판만을 진행하여 100%로 얻을 수 있는 가장 최대의 돈은?
(각 룰렛의 칸이 나올 확률은 1/3이다.)
(단 25%,50%,75%에서 25%는 4판 중 1판,50%는 2판중 1판,75%는 4판 중 3판은 꼭 돈이 나오도록 설계되어있다.)
