3
Q
Mutually Exclusive
A

4
Q
Dependent Probability
A
When the occurrence of an event effects the probability of the other
5
Q
P(A I B) (Conditional)
A
P(A I B) = P(A ∩ B) / P(B)
6
Q
P(A ∪ B) (Conditional)
A
P(A ∪ B) = P(A) + P(B) − P(A ∩ B)
7
Q
P(A I B) (Independent)
A
P(A I B) = P(A)
8
Q
P(A ∩ B) (Independent)
A
P(A ∩ B) = P(A) × P(B | A)
