수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
[창의 퍼즐] [확률] 8*8 체스판에 칸칸이 나누어져 있는 작은 사각형

64개의 정사각형으로 나누어져 있는, 체스판 처럼 생긴 판이 있습니다.
(8*8)
이 때, 랜덤하게 작은 정사각형을 골랐을 때, 판 바깥쪽에 작은 사각형이 접하게 되지 않을 확률은 얼마입니까?
(추가 설명: 체스판이 있을 때, 판 바깥쪽에 그 작은 칸칸이 나누어져 있는 작은 정사각형이 딱 붙어있지 않을 확률을 구하는 것입니다! 분수로 나타내어주시고 풀이는 필수입니다!)
