Misalkan S adalah himpunan mobil,P={Panther,Kijang,Honda,Suzuki},Q={Mercedes,PantherBMW} dan R={Honda,BMW},maka P n (Q υ R)
cantikka
P ={panther, kijang, honda, suzuki} Q={marcedes, panther, bmw} R={honda, bmw} jadi P n (Q u R) = Q u R = {Mercedes, Panther, BMW, Honda} P n (Q u R) = {Panther, Honda}
Q={marcedes, panther, bmw}
R={honda, bmw}
jadi
P n (Q u R) =
Q u R = {Mercedes, Panther, BMW, Honda}
P n (Q u R) = {Panther, Honda}
