Let π΄1, π΄2 and π΄3 be pairwise disjoint events of a result space
Ξ©, each with positive probability of occurrence and
π (π΄1 βͺ π΄2 βͺ π΄3) = 0.4.
Furthermore, let π΅ β Ξ© be another event with π (π΅)> 0. Then:
Item 77 π (π΅) = 0.4 β3, i=1 π (π΅ | π΄i) π (π΄i), true or false
Item 78 P(A3 βͺ B) = (P(BβͺA3)P(A3))Β Β /Β Β P(B).
Β Β true or false
Let 𝐴1, 𝐴2 and 𝐴3 be pairwise disjoint events of a result space Ξ©, each with positive probabilit
