The correct answer is Events that happen over and over form a pattern.
An Event is a collection of an experiment's results. Say, for instance, that you throw a coin as part of an experiment. This experiment's result is whether the coin lands "heads" or "tails." These can be regarded as the events related to the experiment.
Data repetitions in predictable ways are referred to as patterns
Pattern helps to understand the trend of occuring event.
The general format that an event follows is called the pattern.
Pattern cannot exist without a number of events. Events, however, sometimes happen randomly.
Pattern doesn't explain the cause of the event.
Therefore the correct answer is B. Events that happen over and over form a pattern.
