Fundamental counting principle
If one event has m possible outcomes and a second independent event has n possible outcomes, then there are m x n total possible outcomes for the two events together.

4!=(such as 4 × 3 × 2 × 1=24)

Use to estimate the probability of an event.
Each repetition of an experiment is a trail.
The ratio of the number of times that the event occurs.
When the occurrence of one event doesn't affect the probability of the other.
When the occurrence of one event affects the probability of the other.
Process to find dependent events.
