1

Empirical Probability

P(E) = # of times event E occurs /
total # of observed occurrences

2

Theoretical Probability

P(E) = n(E) = # of outcomes in E /
n(S) = total # of outcomes in S

3

P(A and B)
Independent events

P(A) • P(B)

4

P(A and B)
Dependent events

P(A) • P(B | A)

5

P(A')

1 - P(A)

6

P(A or B)
Not mutually exclusive

P(A) + P(B) - P(A and B)

7

P(A or B)
Mutually exclusive

P(A) + P(B)

8

P(B | A)
Conditional

P(A and B) /
P(A)

9

P(A | B)
Conditional

P(A and B) /
P(B)

10

P(B | A)

P(A)
