Step 1 :The question is asking for the probability that a randomly selected person in the region is a woman in the 18-24 age range living alone. From the table, we can see that there are 0.5 million women in the 18-24 age range living alone. The total population of the region is 28.9 million.
Step 2 :So, the probability can be calculated by dividing the number of women in the 18-24 age range living alone by the total population.
Step 3 :\(\text{{probability}} = \frac{{\text{{women\_18\_24}}}}{{\text{{total\_population}}}}\)
Step 4 :Substitute the given values into the equation.
Step 5 :\(\text{{probability}} = \frac{{0.5}}{{28.9}}\)
Step 6 :Simplify the right side of the equation to get the final answer.
Step 7 :\(\text{{probability}} = 0.01730103806228374\)
Step 8 :Final Answer: The probability that a randomly selected person in the region is a woman in the 18-24 age range living alone is approximately \(\boxed{0.0173}\).
