A = {l, a, t, e, r}, B = {l, a, t, e}, C = {t, a, l, e}, D = {e, a, t}

B ⊂ C and C ⊆ A

C ⊆ B and D ⊂ B

D ⊂ A and A ⊂ D

B ⊂ A and C ⊂ D

D ⊆ A and A ⊂ C

**Reiny**, Friday, July 8, 2011 at 12:14amB ⊂ C and C ⊆ A ---- false AND true ---> false

C ⊆ B and D ⊂ B

D ⊂ A and A ⊂ D ---- true AND false ---> false

B ⊂ A and C ⊂ D

D ⊆ A and A ⊂ C

try the others, remember that for

true/false AND true/false , only true AND true ---> true

any other combination is false.
