수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
감나무 열매는 질량이rand(100~250)g이다 나무한그루에 열매 8개가 달리었고, 사람은 (0,0)에 있다
바람의세기는 20m/s이다(바람은 2초에 한번씩분다)
나무는 (-10, 5)~(-10,-5)까지 좌표1에 나무한그루 씩 세워져있다(아주촘촘하다)
이때, 함수f(x,y) = 만약 10 <= M(x,y)이면, 0 아니면, 1이다
M(x,y) = 3x/3y 로 정의한다
이때, 함수f(x,y) = 만약 10 <= M(x,y)이면, 0 아니면, 1이다
f(x,y)가 1이면 떨어지는거고, 0이면 안떨어진다
사람은 (10,0)부터(10,5)까지 5초동안 이동한다
그리고 그자리에서또 (-10,5)까지 5초동안이동한다
이때 감나무열매를 10개이상 맞을 확률은 몇 %인가? (풀이과정!!)
