This illustrates the possibility that certain events that are not readily in our control can still be predicted and prepared for. In other words such events somewhat have a pattern that can be reproduced since they occur in uniform periods of time. This is exemplified by the students ability to predict the occurrences of the "surprise quiz". This could also be illustrated by the weather which albeit not exactly within our control but to some extent can be predicted since it follows a pattern in its occurrences.
