I was watching this video and was wondering how he came up with Px=1/L and Ptheta=2/pi for the probability density functions. Anyone interested should check this out and see if you can explain it? I don't really understand probability density functions I suppose.

Answer 1

Basically he just throws about 100 matches on a table with some lines drawn on it, counted the number of matches that are on the lines and divided the total by the number on the lines and was able to approximate pi very easily, and I would like to understand better how he was able to make those boundary conditions work so well.
