Without examining the theoretical details of this (or any) probabilistic argument (including Bayesian ones), one general approach is this: The theory may all be correct of course (given accepted assumptions), but it's ultimately convincing when results are compared to Monte Carlo computer experiments. (If you don't like don't "trust" your software's random numbers, then you can get some from [ https://www.fourmilab.ch/hotbits/secure_generate.html ]). Say in the case of "In front of you is a jar. This jar contains either 10 balls or 100 balls. The balls are numbered in order from 1 to either 10 or 100." Then you you write a program that randomly creates either a 10ball-jar with probability 0.50 (or any p) or a 100ball-jar with probability 0.50 (or 1-p) and then pick a ball at random. You run this 10,000 times (or whatever) and just get statistics. You can do this for the Monte Hall problem - which has the irony that Monte Carlo "solves" the Monte Hall problem! - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
