To find the probability that a randomly selected person in the city has red hair, we need to divide the number of people with red hair by the total population of the city.
Number of people with red hair = 3,101
Total population = 100,000
Probability (P) = (Number of people with red hair) / (Total population)
P = 3,101 / 100,000
P = 0.03101
To express this as a percentage, we multiply by 100:
0.03101 * 100 = 3.101%
So, the closest option to this probability is:
D. 3%
