Twelve jurors are randomly selected from a population of 3million residents. Of these 3 million residents, it is known that 47% are of a minority race. Of the 12 jurors selected, 2 are minorities. (a) What proportion of the jury described is from a minority race? (b) If 12 jurors are randomly selected from a population where 47% are minorities, what is the probability that 2 or fewer jurors will be minorities? (c) What might the lawyer of a defendant from this minority race argue?
