Bayes¨s theorem and conditional probability

[Toby]

How do these realms work with roulette results?
Is there any situation where it is applied?

[Toby]

I believe that Bayes´s theorem rules work with subjective probability.

Could you please explain "subjective probability"?  To me "subjective" means purely personal as in, "I don't feel Obama loves me".  That is a purely subjective statement.  Probability is what it is.  How can it be subjective?

Bayes has placed a link to understand what Bayes¨s theorem is about.
The horse races example clarify the rule.
We need a roulette example.

Anyone knows the relation between Bayes Theorem and the multinomial Dirichlet distribution applied to roulette result predicctions?
