|
Experimental probability |
P(E)= Number of times the desired outcome occurred divided by total number of trails |
|
|
Theoretical Probability |
P(specific outcome)= 1 divided by n(s) |
|
|
Probability of an outcome |
P(specific outcome)= f divided by n(s) |
|
|
Mutually exclusive events |
P (A or B)= P(A) + P(B) |
|
|
Non-mutually exclusive events |
P (A or B)= P(A) + P(B) - P(A and B) |
|
|
Independent events |
P(A and B)= P(A) x P(B) |
|
|
Dependent events |
P(A and B)= P(A) x P(A|B) |
|
|
Permutation |
nPr= n! divided by (n-r)! |
|
|
Combination Order of selection is not important |
nCr = n! divided by (n-r)!r! |
|
|
Additive counting principle |
n(A U B)= n(A)+n(B) - n(B n A) |
|
|
Multiplicative counting |
n( A U B)= n(A) x n(B) |
