A total of 8 popular brands of cola are to be used in a blind taste study for consumer recognition. (a) If 5 distinct brands are chosen at random from the 8 and if a consumer is not allowed to repeat any answers, what is the probability that all 5 brands could be identified by just guessing? 56 (b) If repeats are allowed in the 5 brands chosen at random from the 8, and if a consumer is allowed to repeat answers, what is the probability that all 5 brands are identified correctly just by guessing? 1 C(10,3) may be written to express 10 choose 3, and P(10,3) may be written to express 10 permute 3.
