Hello. I am having problems with this prob question, thanks for your help:
The judge comes to know the result x of the test of DNA of the accused person. If guilty, the probability of x is 90%. If innocent is 5%.
Which condition on the probability of x, subject to the two events G and I has to be satisfied so that the final probability atributed by the judge to the innocence I is 100%.
the book says P(x|G)=0. Why? I can't get it. Thank you very much.
