함께 풀고 싶은 문제
나도 수학쌤 문장제 문제를 변형해 문제를 내는 곳입니다.
[문장제 문제&개념응용] 원과 정사각형

좌표평면 위에 대각선의 교점이 (0, 0)이고 한 변의 길이가 n인 정사각형이 있다.

이 평면 위의 임의의 한 점을 중심으로 하고 반지름이 r인 원을 그릴 때, 이 원과 정사각형의 교점이 k개가 나올 확률을 P(k)라고 하자.

 

P(k)를 n, r, k로 표현하라.

이 문제 어떠셨나요?

글쎄요

      원의 중심은 좌표평면의 임의의 점에 있습니다, 다시말해 원의 중심은 사각형 내부, 변 위, 외부 어디에도 있을 수 있습니다
