Fundamental Counting Principle – (a multiplication method for finding all possible combinations) – A method used to calculate all of the possible combinations of a given number of events

This is an excellent site for a short video explaining how to use the fundamental counting principle:

 Nutshell Math does have a sample list of math glossary terms that can be accessed without signing up for a free trial. Each glossary term is explained simply and clearly.

 Probability – (the chance of something occurring) – The likelihood that an event will occur

 Independent Event – (events not dependent upon one another) – Events in which the outcome of one event does not affect the outcome of the other event

 

 Now you know that the probability of a heads-up landing when you flip a coin is 1/2.

 What is the probability of getting tails if you flip it again?
It is still 1/2.
 

The two events do not affect each other. They are independent.

 

 

 

 

 

 

Dependent Event – (events that rely on previous outcomes) – Events in which the outcome of one event affects the outcome of the other event.
