x=y*z
|
|
|
Permutation
|
n!
|
|
|
Permutation of a Subset
|
n!/(n-r)!
|
|

n!/(q1!+q2!+qn!)
|
|
|
Circular Permutation
|
n!/n=(n-1)!
|
|
|
Combination

|
|
|
Outcome
|
The possible result of a probability experiment
|
|
|
Event
|
All outcomes that are of interest
|
|
|
Sample space
|
the list of all possible outcomes
|
|
|
Probability
|
the number of ways an event can occur divided by the total number of outcomes
|
|
|
Theoretical probability
|
probability based on population
|
|
|

|
Union
|
A OR B
AUB |
|
|
Intersection
|
A AND B
A^B |
|
|
Union & Intersection Formula
|
p(AUB)=p(A)+p(B)-p(A^B)
|
|
|
Mutually exclusive
|
2 events that cannot occur at the same time; p(A^B)=0
|
|
|
Independent Events
|
knowing A occurred doesn't change the probability
|
|
|
Dependent Events
|
knowing A occurred changes the probability
|
|
|
Dependent events formula
|
p(A^B)=p(A)*p(B|A)
|
|
|
Independent events formula
|
p(B|A)=p(B)
|
