(A) If 3 distinct samples are chosen at random from the 9 types and if the technician is not allowed to repeat any answers, what is the probability that all 3 could be correctly identified by just guessing? Let the sample space S be the set of ways that the 3 distinct samples can be chosen from the 9 standard classifications. The number of elements in the sample space S is n(S)=|: (Type a whole number.)
