Visitors to Yellowstone naturally want to see Old Faithful erupt, so the interval between eruptions becomes a concern for those with time constraints. If we randomly select one of the times represented in the table, what is the probability that it is at least one hour?

Use the data in the accompanying table, which summarizes a sample of 200 times (in minutes) between eruptions of the Old Faithful Geyser in Yellowstone National Park.
