P(F) (2)
Thus, using (2), the independence of two events is also defined as follows:
Definition 3 Let E and F be two events associated with the same random experiment,
then E and F are said to be independent if
P(E ∩ F) = P(E) P (F)
Remarks
(i)
Two events E and F are said to be dependent if they are not independent, i e
