Rules of Probability
|
Addition Rule and Multiplicaiton Rule
|
|
|
Addition Rule
|
P(A or B)= P(A)+ P(B); Assumes mutually exclusive outcomes the probability of all outcomes is 1
EX: Probability of rolling a die and getting a 2 or 4 |
|
|
Multiplication Rule
|
Independent outcomes: The occurence of one does not change the liklihood of the other.
EX: P(heads on both coins)= P(heads 1st) * P(heads 2nd) (.5)*(.5)=.25 |
