Final answer:
The proportion of the jury described from a minority race is 44%.
Step-by-step explanation:
To find the proportion of the jury described that is from a minority race, we need to calculate the number of jurors from a minority race out of the total number of jurors selected.
Given that 44% of the 5 million residents are of a minority race, we can calculate the number of residents belonging to a minority race as (44/100) * 5,000,000 = 2,200,000.
Since 12 jurors are selected randomly from the population of 5 million residents, the proportion of the jury described from a minority race is (2,200,000/5,000,000) = 0.44, or 44%.
