Fundamental counting principle - how to calculate?
Choose one item from group a group of “M” items, and a second item from group of “N” items, then total number of choices is M•N. (Same as M X N)
What is found by using the fundamental counting principle?
Counting possible outcomes
Permutation
Occurs when no item is used more than once and the order of arrangement makes a difference.
Combinations
Occurs when no item is used more than once and the order of items makes no difference.
Sample space
The set of all possible outcomes of an Experiment
Event
Any subset of a sample space. For example the Event of landing tails up when a coin is tossed.
