Final answer:
The probability that a randomly selected person owns a non-white vehicle is 11/13 or about 0.85.
Step-by-step explanation:
To find the probability that a randomly selected person owns a non-white vehicle, we need to first determine the total number of people who own cars or trucks.
Given that there are 9 people who own trucks and 4 people who own cars, the total number of people who own vehicles is 9 + 4 = 13.
However, 2 people own either a car or truck that is white. So, the total number of people who own non-white vehicles is 13 - 2 = 11.
Therefore, the probability that a randomly selected person owns a non-white vehicle is 11/13 or about 0.85 (rounded to two decimal places).
