an event or outcome that cannot be further broken down
|
A simple event
|
|
|
For a sequence of two events in which the first event can occur in m ways and the second can occur in n ways, the events together can occur a total of
|
m x n ways.
e.g., 2 dice = 6 x 6 = 36 ways |
|
|
The number of permutations (or sequences) of r items from n available items (without replacement) is:
|
nPr = n!
(n-r)! For three letters ABC: 3x2x1 = 6 (3-3)! |
|
|
If order or sequence is not important, one can determine the number of different combinations by
|
Cn = nCr = n!
(n-r)!r! e.g., the letters ABC – C3 = 3!__ (3-3)!3! = 1 the letters (different pairs of 2): C2 = 3! (3-2)!2! = 3 |
