A laboratory technician is to be tested on identifying blood types from 8 standard classifications. Complete parts (A) and (B) below.(A) If 3 distinct samples are chosen at random from the 8 types and if the technician is not allowed to repeat any answers, what is the probability that all 3 could be correctly identified byjust guessing?Let the sample space S be the set of ways that the 3 distinct samples can be chosen from the 8 standard classifications. The number of elements in the sample space S is n(S) =(Type a whole number.)
