Question
(a) Be A. and B. Events in a finite probability space (N, P), so that
P(A) = 0, 6, P ( B) = 0, 5 and P ( A. N B) = 0, 2. Calculate P ( A I B), P ( B I A) and
P(A. U B).
(b) Let now be in the situation from (a) C. another event with P ( C) = 0, 3 and it applies
C.n(A. A B) = Ø. Show that P (CI(AU B)) is already clearly determined by this information, and
calculate this probability.
