So you mean the place from which you drop the balls is the mean value of the gaussian distribution?

Yes, if you're dropping the beans in the centre. If you drop them at the right edge then you'll only get the left half of the Gaussian. Here's a challenge: where will the mean be?So you mean the place from which you drop the balls is the mean value of the gaussian distribution?

It will still be at zero?

No, must be closer to the edge where the beans are dropped in. http://en.wikipedia.org/wiki/Half-normal_distributionIt will still be at zero?

Thanks a lot.

I saw one of those years ago. It's very impressive. The marbles make random bounces to the left or the right; but organize themselves neatly into a bell curve. How do they know how to do that? It's a demonstration that really brings math to life.
