In that case, I'll go ahead and just say what I consider the answer to be.

If you flip a coin n times and you get n-1 Tails from those flips, what is the probability that the coin is biased?

Alternatively, you could just do what biologists do. Calculate a p value, and if it's less than 0.05 then consider that to be proof that the coin is biased. I think p<0.05 for n>7 based on bonanova's formula.

Yeah. What he said. Prior ... Something.

Bushindo explained Bayes to me once before, plasmid just did again,

but it's still not something I could explain to my grandson.
