I think, for a majority of people, it would be an easier way to study probability. Visualization makes things much more understandable than algebraic formula derivation.
Yea maybe I am bit biased about my opinion because I understood probability easier using visual examples, but people who I have interacted with mostly also understand things easier in the visual form. So I think it maybe _the_ best method to teach probability because it will reach out to a majority of people, ofcourse, there might be people who might understand it better if explained in a different way, but that maybe a minority, so all the different methods can be tried out in school.
One more thing I would like to add is that everyone has a biased opinion of things based on their perception of the world and that's why I think there should be debates. Generalizing from examples and experiences is a natural method developed during evolution.
If a kid touches a hot plate and experiences pain, I think it is perfectly valid that it should generalize that to all other hot plates. :)
Does it? Are you http://lesswrong.com/lw/dr/generalizing_from_one_example/ ?
