Probability Flashcards
Sample Space
Set of all possible outcomes
Probability
Outcome of a random phenomenon is the proportion of times the outcome would occur in a very long series of repetition
Venn Diagram
Probability
Represents probability using area (2+ events)
P(S)=1

Independent
One event does not change the probability of another event
P(S)=1
Area within a venn diagram
P(A&B)=P(A)P(B)
Testing for Independence (Probability)
P(AorB)=P(A)+P(B)-P(A&B)
Disjoint/Mutually Exclusive
Conditional Probability
The probability of A, given B

Complement of an event
(1-p)
Mutually Exclusive/Disjoint
Events cannot occur at the same time
Continuous Random Varibale
Graphed by a density curve (ex. normal curve)
Discrete Random Variable
x has a amount that is countable for possible values
Binomial Distribution
