Fundamental Counting Principle
The Fundamental Counting Principle states that
the total number of outcomes in a compound
event can be found by multiplying the number of
outcomes of each event.
Example:
Use the Fundamental Counting Principle to find
the total number of outcomes when a coin is
tossed and a number cube is rolled.

Example:
Find the total number of outcomes from rolling a number
cube and choosing a letter from the word NUMBERS. Then
find the probability of rolling a 6 and choosing an M.

Find the number of different outfits that can be
made from 3 sweaters, 4 blouses, and 6 skirts. Then
find the probability of randomly selecting a
particular sweater-blouse-skirt outfit. Is the
probability of this event likely or unlikely?
Sweater  Blouse  Skirt = Total
3  4  6 = 72

P(outfit) =
72
This event is unlikely to happen.
