수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
어느 성능이아주좋은 화염방사장치가있다 화염방사장치를 t초동안 나무목제 부피∞cm^3에 쏘아되었다
조건 i)화염방사기를 방사한동안 타는목제의 부피: 0.5t + 1
조건 ii)화염방사기를 사용한뒤 타는 목제에 부피 0.05s+2
하지만 주변은 아주차가워서 5/x만큼 불길이식는다 (불길이식으면, 타는목제부피-타는목제부피 * 5/ x+ 랜덤(0.3~1)단소수점은 한자리)
그리고 방사한다음 10초뒤에는 무조건 소화기를 뿌려서 꺼버린다
문제1. x = 10, s = 10, t = 10일때 탄 목제 부피가 10cm^3이상일확률
문제2.x = 13, s = 1~2, t = 50일때 탄목제 부피가 100cm^3이하일확률
