List 3 factors that can influence probability.
1. Sample Size: The size of the sample can influence the probability of an event occurring. Generally, a larger sample size can result in more accurate probability estimates. 

2. Event Dependency: The relationship between events can influence their probability. If two events are dependent, the occurrence of one event can impact the probability of the other event happening. 

3. Variation: The amount of variation within the data or outcomes can influence probability. For example, if an event has a large number of possible outcomes or significant variability, it may be more difficult to accurately estimate the probability of the event occurring.
