想問這題(2小題)的解體思路 麻煩各位了
3.13. A detective has evidence that 2 persons were
involved in the crime he is investigating. Three suspects
with very similar criminal records were seen close to the
crime scene. Two of them are believed to be guilty. What
is the probability that the first suspect being interviewed is
guilty?
Considering that the detective has managed to confirm
one interviewee as having been involved in committing the
crime, what is the probability that the next person to be
interviewed is innocent?
