Refer to the probability distribution table below and find the indicated probabilities. F 0 1 2 3. P(z) 0+ 0+ 0+ 0+ 4 0.0002 5 0.0013 6 0.0073 7 0.0305 8 0.0931 0.2021 10 0.296 11 0.2627 12 0.1069 9 Find the probability of exactly 6 Mexican-Americans among 12 jurors. Round your answer to four decimal places. P(r= 6) = Find the probability of 6 or fewer Mexican-Americans among 12 jurors. Round your answer to four decimal places.
