드디어 소스가 올라가네요 !! 짬짬히 만든코드라 조금 난잡합니다

베팅하는 프로그램입니다.

1회배팅 만원에 지면 2만원 또지면 4만원 이렇게 확률을 키워나가는 프로그램입니다.

그런데 rand값이 고르게 분포하지 못해서인지 200회를 넘지 못하네요 ㅜㅜ

확률이 너무 극단적이라고해야되나?.... 연속으로 지는 횟수가 많을수록 확률은 극격히 떨어질텐데말이죠...

200판도 안되서 14~15번 연속으로 질확률이 나온다는건 의심이 많이됩니다 ㅠㅠ

시뮬레이션을 제대로해보고싶습니다.

랜덤값을 좀더 고르게? 이쁘게? 분포해주고싶습니다. 조언부탁드려요~
