Final answer:
The answer for the maximum on-duty driving hours in a 14-day cycle for drivers is 120 hours. The remaining questions involve applying principles of uniform distributions and binomial probability to find specific probabilities related to distances traveled and days worked.
Step-by-step explanation:
Drivers on a 14-day cycle must not drive after 120 hours of on-duty time in 14 consecutive days. The correct answer to this question is option (d). The probability questions, such as the number of miles driven by a truck driver and the probability inquiries about Janice, Roberta, and Barbara driving on certain days, represent typical problems found in a statistics course, requiring an understanding of probability distributions and combinatorics. Additionally, the question about the probability of waiting more than a certain time for an event to occur also involves understanding and calculating probabilities.
Subjects covered in this type of question could be linked to topics like uniform distributions, binomial probability, and statistical calculations. The questions often involve real-world contexts to help students grasp the application of mathematical concepts.
