Problema Solution
22% the cameras sold in the United States are made in Japan. If a store sells 20 cameras in one day, what is the probability that 8 were made in Japan?
Answer provided by our tutors
The problem statement is ambiguous... a 0.22 probability of purchasing a Japan camera could be stated if all other possible selections are available at that store... the probability of purchasing 8 Japan cameras on the same day could be expressed as a decimal probability (0.22^8)*100
0.000548
So if that approach is taken (AND-rule for probabilities), then the probability is about zero.
