i) ل (A Y ب ) = ل (ا ) + ل (ب ) - ل (A □ ب )
= \frac{1}{2} + \frac{5}{6} - \frac{5}{12} 0.5
ى ل (YA ب)= \ 0.5\frac{11}{12}
ii) ل( YA ب) = 1- ل (YA ب ) 0.5
= 1- \ 0.5\frac{11}{12} = \ \frac{1}{12}
iii) ل (YA ب) = ل (ا) + ل (ب) - ل (A □ ب )
= \ \frac{1}{2} + \ \frac{5}{6} - ( \ \frac{5}{6} - \ \frac{5}{12} ) 0.5
=\ \frac{11}{12} 0.5
