Odpowiedź:
Ω ={ 1,2,3,4,5,6,7,8,9 }
A = { 2,4,6.8}
B = { 6,7,8,9 }
B ' = Ω \ B = { 1,2,3,4,5 }
A ' = Ω \ A = { 1, 3,5,7,9 }
A ' ∪ B = { 1, 3,5,6,7,8,9 }
więc
P ( A ) = [tex]\frac{4}{9}[/tex] , P( B ') = [tex]\frac{5}{9}[/tex] , P( A' ) = [tex]\frac{5}{9}[/tex] P ( A ' ∪ B ) = [tex]\frac{7}{9}[/tex]
