When he plugged that wind-force equation into his model and assumed that the probability of a branch breaking due to wind stress is constant, he came up with Leonardo's rule.

他将风力公式应用到他的模型中，并假定树枝受到风力作用而断裂的概率是恒定不变的，据此他推导出了达·芬奇公式。

If the probability of observing a car in 30minutes on a highway is 0.95, what is the probability of observing acar in 10 minutes (assuming constant default probability)?

如果在高速公路上30分钟内到一辆车开过的几率是0.95，那么在10分钟内看到一辆车开过的几率是多少(假设为常概率条件下)？
