Final answer:

The question involves calculating probabilities for events given different statistical distributions such as normal and exponential at the college level. It requires using z-scores and understanding of probability distributions.

Step-by-step explanation:

The subject of this question is Mathematics, specifically probability and statistics, and the grade level is College. The questions provided relate to finding the probability of events occurring within a specified time frame.

For instance, question 79 focuses on the probability that a randomized criminal trial will last more than 24 days. Given a normal distribution with a mean of 21 days and a standard deviation of 7 days, it can be calculated using the z-score formula. Similarly, question 100 pertains to an exponential distribution where we calculate the probability of fewer than seven visits to a website within a one-hour period.

These problems typically require the use of probability distribution functions, and an understanding of how to compute probabilities for both the normal and the exponential distributions.
