Hello all,
I got stuck with some problem of probability
What I understand is how to verify by statistics, that a die (is that really the singular of dice ??) is crooked:
- cast it a number of times, say twenty
- count the number that shows most, say we find eight times the six
- compute probability of this result for an unforged die with 1/6 propability for each number, if I entered my figures properly, then p (k = 8) = 0.0084
so we have a signifcance of about 1 %, that means probability for the die to be forged is 99 %.
What I could not figure out is how to proceed to verify that the die is straight. Something like how often must the number show at least to prove it. But in all my musings I come back to the binomial probability function and come out with the same figures I used to verify it is forged.
Any ideas ?
Thanks in advance.
