Question

An individual is presented th three different glasses o cola, labeled , D and P. He is asked to taste all three and he list hem in order of re erence suppose the same cola as act al been put to all three gla ses. (a) What are the simple events in this ranking experiment? (Enter your answer in set notation.) What probability would you assign to each one? O All of the simple events have the same probability, O The probability of an individual event where D is ranked first is The probability of another individual event is 15 All of the simple events have the same probability, O The probability of an individual event where D is ranked first isThe probability of another individual event is O It is impossible to determine the probability of the simple events with the given information. 12 (b) What is the probability that C is ranked first? (Round your answer to three decimal places.)

Explanation / Answer

a) simple events are S ={ CDP,CPD,PDC,PCD ,DCP,DPC}

all the simple eents have the same probability 1/6

b)P(C is ranked first)=2/6 =1/3 =0.333

c)P(C rank first and D ranked last)=1/6 =0.167
