Buffon-Laplace Needle Simulation

Follow these steps to experience the simulation:

1. Set the needle length l and grid spacings a, b. For the classical formula to apply, ensure l ≤ min(a, b).
2. Set N, the number of needles to drop in one batch.
3. Click Drop One Needle to observe a single trial and its result.
4. Click Run N times to run a batch and compare the empirical probability with the theoretical probability.
5. Try increasing N to see the empirical result become more stable.
6. Click Reset or change any parameter to start fresh.
