In a homicide case 33 different witnesses picked the same man from a line up. the line up contained 5 men. if the identification
s were made by random guesses, find the probability that all 33 witnesses would pick the same person. round to seven decimal places.
1 answer:
the correct question in the attached figure
<span>
we know that
</span>the probability
that a witness picks a particular person by chance-----> P=1/5
the probability
that all 7 witnesses would pick the same person-----> P=1/5^7=0.0000128
the answer is the option B 0.0000128
<span>There are a variety of problems in which the number of witnesses change, for example
</span><span>....find the probability that all 9 witnesses would pick the same person
</span>in this case, the probability would be-------> P=1/5^9=0.000000512<span>
