Theoretical Prob.: P(event)= # of favorable outcomes

                                   # of outcomes sample space(total) 
Complement: P(E)=1-P(not E)
Permutations(order matters):nPr= n!      
                                                       n-r!
*n= total and r= specific
Combinations: nCr= n!
                             r! X (n-r)!
Independent: Occurence of one event doesn't affect others
*P(A and B)= P(A) x P(B)
Dependent: one impacts another (ex: sum is greater than 9 AND a red cube shows a 5)
*P(A and B)= P(A) x P(B|A)

Two-Way Tables:
*Joint relative frequencies: are the values in each category divided by the total #
*Marginal relative frequencies: found by adding the joint relative frequencies in each row/column

*Mutually Exclusive Events (can't occur at the same time)
P(AUB)=P(A+P(B)
*Inclusive Events (one or more outcomes in common)
P(AUB)=P(A)+P(B)-P(AB)
