A
P(AnB) = P(A) x P(B)
When one event has no effect on the other
2
Q
Mutually exclusive
A
P(AnB)=0 , P(AuB)= P(A) + P(B)
when one event has no effect on another
They don’t overlap
3
Q
Conditional probability
A
P(AIB) = P(AnB) / P(B)
if one event effects the outcome of another event
4
Q
Addition formula
A
