'Snake-Eyes ' Joe (Posted on 2008-07-28) Difficulty: 3 of 5
"Snake-Eyes" Joe introduced a die of his own into a game of chance.

He was subsequently challenged that the die was biased.

Very rigorously test to see if there are grounds to substantiate this claim; don't accept just two or three trial runs. Are you able to offer a theoretical model consistent with your findings?

Test "Snake-Eyes" Joe's Die with this simulator which has a run of 60,000 at a time:

No:123456Total
Scores 0 0 0 0 0 0 0

I've taken this to levik.

I kept much of my prior offer with the view that others may be more careful in trusting a computer listing of one's thoughts. 

Even changing the "tn" counter to discriminate at "9" gives me no solace!
