Relative Frequency Method

Numbers of times E occurs / total number of observations

2

Numbers of times E occurs / total number of observations

Relative Frequency Method

3

Permutation

Order matters- P = n! / (n-r)!

4

Order matters- P = n! / (n-r)!

Permutation

5

Combination

Order does not matter C = n! / r!(n-r)!

6

Order does not matter C = n! / r!(n-r)!

Combination

7

Complement Rule P(E) - P(EnF) =
1 - P(E) =

P(En~F) = P(E) - P(EnF)
P(~E) = 1 - P(E)

8

P(En~F) =
P(~E) =

Complement Rule P(E) - P(EnF)
1 - P(E)

9

Addition Rule P(E) +P(F) - P(EnF) =

P(EuF)

10

P(EuF) =

Addition Rule P(E) +P(F) - P(EnF)

11

Multiplication Rule P(EnF) =

P(E) x P(F|E)
P(F) x P(E|F)

12

P(E) x P(F|E) =
P(F) x P(E|F) =

P(EnF) =

13

Proof Of Independent events

1.) P(A|B) = P(A)
2.) P(AnB) = P(A) x P(B)

14

1.) P(A|B) = P(A)
2.) P(AnB) = P(A) x P(B)

Proof Of Independent events

15

Conditional Probability of A, given B

P(A|B)

16

P(A|B) is a conditional probability for

A, given B

17

P(~A) x P(~B|~A) =

P(~A n ~B)

18

P(~A n ~B) =

P(~A) x P(~B|~A)

19

P(~A) x P(B|~A) =

P(~A n B)

20

P(~A n B) =

P(~A) x P(B|~A)

21

P(A) x P(B|A) =

P(A n B)

22

P(A n B) =

P(A) x P(B|A)

23

P(A) x P(~B|A) =

P(A n~B)

24

P(A n~B) =

P(A) x P(~B|A)

25

coefficient of variation

ratio of standard deviation to mean. SD/MEAN (smaller ratio means less variation)

26

ratio of standard deviation to mean. SD/MEAN (smaller ratio means less variation)

coefficient of variation
