Final answer:
The provided question about PTS subsidizing a U-Pass is unrelated to the subsequent statements, which discuss probabilities and percentages in different contexts. Without specific information about the percentage of students receiving $250 or more, the question cannot be answered.
Step-by-step explanation:
The question "How much does PTS subsidize a semester or annual U-Pass?" does not pertain to the information provided. However, to address the provided statements, the sample scenarios given are all about probabilities and percentages related to various real-world contexts. For instance, when dealing with the scenario about the sample of 200 students, to find how many are expected to receive $250 or more, relevant information must be presented to answer this, such as a probability or percentage of students who receive that amount—without this, the question cannot be reliably answered.
