Probability and Normal Distribution

In the study of statistics, probability is a key concept that illustrates and describes the randomness and likelihood of an event from happening given the number of ways it can happen and the number of outcomes that this event could probably happen. That is, probability in statistics helps determine how likely an event is going to happen, as the certainty of the event happening cannot be determined specifically and how many times, but the likelihood of it happening can be determined. Using probability for the researcher, statistician or business decision-maker would mean going through all possible outcomes for an event or outcome to happen.
