The Fundamental Counting Principle helps when determining the sample space of probability since it figures out the total number of ways the combination of events can occur. Thus, it is used as a guidance when determining the sample space of a probability.
In order to compute the probability of an event, you need to know the number of outcomes in the sample space and the number of outcomes in the event. ... The Fundamental Counting Principle works similarly for more than two events - multiply the number of outcomes in each event together to find the total number of outcomes.
