- Conditional Probability
If E and F are two events associated with the same sample space of a random experiment, the conditional probability of the event E given that F has occurred, i.e. P (E|F) is given by
$P(E \mid F)=\frac{P(E \cap F)}{P(F)}$ provided $P(F) \neq 0$
-
Properties of conditional probability
Property 1 P(S|F) = P(F|F) = 1
Property 2 If A and B are any two events of a sample space S and F is an event of S such that P(F) ≠ 0, then
P((A ∪ B)|F) = P(A|F) + P(B|F) – P((A ∩ B)|F)
Property 3 P(E′|F) = 1 − P(E|F)
