원형파이와 원형, 파이 셋 중 한 명은 내일 아침에 1억이라는 큰 상금을 받기로 되어있습니다.
누가 받을지는 이미 결정되어 있지만 그들 셋은 자기들 중 누가 받는지 모릅니다.
너무 궁금해져서 원형파이는 관계자에게 물어봤습니다.
원형파이 : 내일 상금을 받는 사람에 대한 정보를 조금만 주실 수 있나요?
관계자 : 뭐, 최대한 공평한 정보를 드리죠. 내일 상금을 받는 사람은 파이가 아닙니다.
이 때 원형파이는 생각했습니다.
'일단 상금을 받는 사람 중 파이는 없으니, 나 아니면 원형이네. 그럼 50% / 50% 군. 그렇다면 동전 던지기의 확률로 볼 만 하겠는걸?'
과연 원형파이는 맞을까요?
아니라면 어떤 점이 틀릴까요?
그 부분은 어떻게 바뀌어야 맞는 말이 될까요?
