My two cents about statistics:
Yes, this is true that statistics can't provide you with information that something is impossible or you can expect something for sure. But statistics indeed gives us a mechanism to check whether some events are reasons of another. Just as an example I'd like to mention Mendel's test. He researched peas round(R)-wrinkled(W) and yellow(Y)-green(G). And he had a hypothesis that probabilities of random taken pea to be RY - 9/16, WY - 3/16, RG - 3/16, WG - 1/16. During an experiment he took randomly 556 peas and got RY - 315, WY - 102, RG - 108, WG - 31 (Found these notes in my old exersize-book from statistics). The question was whether these data confirm theory or disprove it. Statistics proves that these data confirm theory, moreover they were so "nice", that a lot of scientists think - Mendel's apprentice falsificated results of experiment.
Conclusion: Yes, statistic data could not provide you with an information about one particular terrorist to be muslim or not, but in general it indeed could establish some relations between different groups and give information about distributions in the group by subgroups, etc.
