2) B={(1,6),(6,1),(2,3),(3,2)} , /B/=4
3) /ω/=6*6=36
P(A`)=1-P(A)=1-6/36=1-1/6=5/6
4) P(B`)=1-P(B)=1-4/36=1-1/9=8/9
5) AnB={(1,6),(6,1)}, /AnB/=2
P(AnB)=2/36=1/18
6) AuB={(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)(2,3),(3,2)} , /AuB/=8
P(AuB)=8/36=2/9
Prawdopodobieństwo AuB możemy także obliczyć ze wzoru;
P(AuB)=P(A)+P(B)-P(AnB)
P(AuB)=6/36+4/36-2/36=8/36=2/9
