Assume that the amount of time that it takes an employee to service a car at an oil change facility follows the uniform probability distribution between 21 and 38 minutes. What is the probability that a randomly selected car will require between 25 and 35 minutes to service?

The uniform distribution probability is calculated as (x - a) / (b - a), where x is the range of interest (35 - 25 = 10 minutes), a is the minimum value (21 minutes), and b is the maximum value (38 minutes). Thus, the probability is 10 / (38 - 21) = 10 / 17 = 0.5882.
