Does anyone have any idea how magicians/illusionists predict things (like on the new show Phenomenon)?

Have you all been watching Phenomenon? I have seen illusionists do many of these tricks before and obviously there is an explanation somehow... even Criss Angel admits everything is an illusion and there is no real "magic". But I am very curious if anyone knows how they do things like pick random audience members (by throwing frisbees! seems truly random) and the people can pick any three objects (in the murder mystery) and the illusionist has those three things already written on a scroll hanging above the audience! From Phenomenon it was Tom Hanks, killing someone with a dresser, in Hawaii. Any thoughts on how they do that? I cant believe the audience is in on it because someone would confess and take the money a tabloid or website would offer them to tell us how its done! So whats the deal??
