Final answer:
The question pertains to calculating probabilities, a mathematical concept often encountered in high school. A definite answer cannot be provided without additional context or likelihood data regarding the event of 'more than 4 students waiting'.
Step-by-step explanation:
The student's question is asking for the probability of an event occurring, which falls under the subject of Mathematics, specifically within probability and statistics. In the examples provided, each scenario illustrates a different probability problem, such as the time to find parking, the distance a student lives from campus, or attendance at an event. To solve such problems, one would typically use knowledge of probability theories and calculations, which might involve the use of binomial distribution, conditional probability, or expected values.
Without the specific context or data for the initial question (probability of more than 4 students waiting), it's impossible to provide a definite answer. However, the solution would generally involve calculating the number of successful outcomes where more than four students are waiting, divided by the total number of possible outcomes, assuming all necessary probabilistic information is given.
