Given the following sets, select the statement below that is true.
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

  • Math - ,

    B ⊂ 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.

    This one is particularly confusing to me :/
