C. is wrong

n a homicide ca 4 different witnesses picked the same man from a line up. The line up contained 5 en. If the identifications were made by random guesses, find the probability that all 4 witnesses would pick the same person. O A. 0.0080000 O B. 0.0016000 O C. 0.0009766 O D. 0.8

Solution

The 1st person can pick anyone. the remaining 3 must each pick the same person, with Pr = 1/5,
thus by the multiplicative principle,
indicated Pr = (1/5)³ = 1/125= 0.008000
