라임의 집 근처에는 개천이 있다.
이 개천은 겨울이 되면 얼게 되는데,
온도가 음수인 상태에서
온도의 절대값의 루트배에 비례하여 두께가 결정된다.(단위 cm)
이제, 어는 범위를 5 * 5 = 25m2로 제한하자.
두께의 오차는 양음 2cm이며, 이는 각 1m2마다 일어난다.
이때, 라임은 이 위에서 뛰어다니면서 놀려고 한다.
그러면서 최소 10칸은 밟게 되는데, 두께가 10cm 이상인
얼음만이 밟았을때 깨지지 않는다고 한다.
오차 발생률은 온도의 제곱배에 비례하고, -10도 이상은 모든 얼음에
오차가 발생한다. 이때, 라임이 빠질 확률이
45%이하로 처음 떨어지는 온도는?
